Custom hiking backpack and bags manufacturer types of hiking backpacks

A hiking backpack is one of those products that can look convincing in photographs long before anyone knows whether it actually works. A clean silhouette, technical-looking webbing and thick shoulder padding can create the appearance of performance, yet none of these details proves that the pack will remain stable after several hours under load. The real difference appears when the backpack is filled, adjusted and carried.

That is why product development should begin with the intended trip, equipment volume and realistic carried weight—not with color, logo placement or even fabric denier.

A custom hiking backpack program can include daypacks, ultralight packs, hydration packs, overnight bags, multi-day trekking packs, expedition backpacks and mountaineering packs. The right type depends on trip duration, usable capacity, realistic carried weight, torso fit, suspension structure, ventilation, weather exposure and equipment attachment needs. As volume and load increase, frame support, hip-belt transfer, reinforcement and sample testing become increasingly important.

A 24L daypack and a 65L trekking pack may both use nylon, mesh, foam, zippers and buckles, but they should not be treated as the same construction enlarged to different dimensions. A larger shell encourages more weight to be carried. Once the intended load rises, shoulder geometry, hip-belt placement, back-panel stiffness, load lifters, compression and seam reinforcement begin to determine whether the product is merely spacious or genuinely usable.

For established outdoor labels, this distinction affects far more than comfort. It affects sample revisions, material consumption, sewing time, hardware selection, unit cost, testing scope, carton weight and even product-return risk.

Jundong’s backpack development capability includes capacity, compartments, shoulder straps, back padding, side pockets, chest buckles, reflective details, load-bearing structure and comfort-related details, using materials such as polyester, nylon, Oxford fabric, RPET, mesh, foam padding and lining fabrics.

The most productive first discussion is therefore not, “How much is a 40L hiking backpack?” It is, “What should this 40L backpack carry, for how long, and how should that weight sit on the body?” That one change can prevent weeks of revisions later.

What Types of Hiking Backpacks Are There?

Hiking backpacks are usually grouped by trip length, usable volume, expected carrying weight, support structure, and activity. Capacity alone is not enough. Two packs with the same 35L volume can behave very differently if one is designed for light clothing and water while the other is expected to carry dense technical equipment. For product development, the practical categories are daypacks, ultralight packs, hydration packs, overnight packs, multi-day trekking packs, expedition packs, and mountaineering packs.

A useful way to compare them is:

Type	Common Capacity	Practical Carrying Focus	Structural Demand	Main Use
Hiking daypack	15–30L	Light essentials	Low to medium	Day hikes
Ultralight pack	20–50L	Low pack weight	Low to medium	Fast/light trips
Hydration pack	5–30L	Water + small gear	Low to medium	Hiking, cycling, trail use
Overnight pack	30–50L	Sleep gear + food	Medium	1–2 nights
Multi-day trekking pack	45–70L	Sustained load	High	3–7 day trekking
Expedition pack	65–90L+	Heavy, bulky gear	High	Extended trips
Mountaineering pack	30–60L	Technical equipment	Medium to high	Alpine and climbing use

These figures are best treated as development references rather than fixed rules. Season, equipment size, clothing volume, food, water, and expected carrying weight can change the appropriate size significantly.

Hiking Daypacks

Hiking daypacks are designed for short outings where the main load is usually water, food, extra clothing, first-aid items, rain protection, and small personal gear.

A 15–20L style is often suitable for short, warm-weather outings. Around 20–30L gives more space for longer day hikes, colder conditions, extra layers, or camera equipment. Larger daypacks can move toward 35L when more gear is required, but at that stage the support system deserves closer attention.

For a commercial daypack, useful design features often include:

• shaped shoulder straps;
• adjustable sternum strap;
• breathable back padding;
• side bottle pockets;
• hydration sleeve;
• front stretch pocket;
• trekking-pole loops;
• light compression straps;
• key clip or small valuables pocket.

The most important design decision is how much support the pack actually needs. A lightweight 18L product may perform well with foam and a basic back panel. A 30L style expected to carry several liters of water, food, clothing, and equipment may benefit from firmer support.

Side-pocket geometry also matters more than it seems. A bottle pocket should be deep enough to hold the bottle while walking, but not so high that the user has to remove the pack to reach it. Elastic tension, pocket angle, and the relationship between the bottle pocket and compression straps should all be checked on a filled sample.

For a product family, daypacks are often the easiest entry into hiking gear, but they should still be developed around real use rather than treated as ordinary casual backpacks with outdoor styling.

Ultralight Hiking Packs

Ultralight hiking packs are built around one central goal: reducing unnecessary weight without removing the structure needed for the intended load.

That requires discipline because almost every component contributes weight:

outer fabric,

lining,

foam,

zippers,

buckles,

webbing,

binding,

reinforcement,

frame parts,

labels,

and extra pockets.

A useful development brief should define three numbers early:

Item	Example
Target volume	28L
Target empty weight	650–750g
Expected carried weight	6–8kg

Those three figures are far more useful than simply asking for “an ultralight hiking backpack.”

If the pack must stay very light, the design may use fewer compartments, shorter zippers, lighter webbing, reduced lining, or strategic reinforcement only in high-stress areas. A full lining, thick foam package, oversized buckles, and multiple organization pockets can quickly push the finished weight far above the original target.

Material choice is important, but the lightest fabric is not always the best choice. If an extremely light shell requires large reinforcement patches at every stress area, part of the weight saving disappears.

The stronger approach is to optimize the whole construction rather than chase one material specification.

Ultralight packs are especially suitable for fast hiking, minimalist travel, and experienced users who deliberately control equipment weight. They are less suitable when the product is expected to carry heavy or unpredictable loads.

Hydration Backpacks

Hydration backpacks are designed around a reservoir system rather than simply adding a water-bladder pocket to an existing backpack.

One liter of water weighs about one kilogram, so a 2L or 3L reservoir creates a concentrated load close to the back. The pack therefore needs to control that weight while keeping the reservoir stable.

Important development details include:

• reservoir sleeve size;
• internal hanger;
• hose exit;
• left/right hose routing;
• shoulder-strap retention;
• filling access;
• separation from electronics or dry items;
• drainage or moisture management.

Compact hydration packs may be only 5–12L and carry little more than water, nutrition, a shell, and small essentials. Larger hiking versions may be 15–30L and combine hydration with clothing, food, and outdoor equipment.

The reservoir should be tested while filled, not empty.

A full bladder can press into the main compartment, change back-panel shape, or interfere with internal support. It may also pull on the upper panel if the hanger position is wrong.

Another useful check is hose routing at different shoulder-strap settings. A tube route that works for one torso size may become too tight or awkward at another adjustment.

For a private-label hydration collection, it is also worth deciding whether the reservoir is included or whether the backpack is only “hydration compatible.” That difference affects packaging, testing, cost, and product communication.

Overnight Hiking Packs

Overnight backpacks sit between daypacks and full trekking packs. This is where load support starts becoming much more important.

A 30–50L volume is commonly used for one- or two-night trips, depending on climate and equipment size.

Typical contents may include:

sleeping bag,

compact shelter,

cooking equipment,

food,

extra clothing,

water,

personal gear.

The extra space increases both volume and weight, which means the back system should be reviewed together with the bag body.

A common development mistake is enlarging a successful 25L daypack into a 40L style while keeping nearly the same harness. The product gains capacity but not carrying ability.

An overnight pack usually benefits from:

• stronger shoulder construction;
• more effective hip support;
• firmer back structure;
• upper and lower compression;
• bottom reinforcement;
• external gear attachment;
• larger but controlled main volume.

Physical load testing is especially useful here.

Put representative equipment into the prototype and check whether the pack remains stable when partly filled and fully filled. Watch whether heavy items pull away from the back and whether compression straps actually bring the load closer to the body.

This category is often ideal for outdoor labels that want a more technical product without entering the complexity of a full 60–70L trekking system.

Multi-Day Trekking Packs

Multi-day trekking packs are built for sustained carrying over several days, so the suspension system becomes one of the most important parts of the product.

Around 45–70L is a common working capacity for this category, although equipment volume and trip style can shift the requirement.

Typical loads may include:

tent or shelter,

sleeping system,

food,

cooking equipment,

clothing,

water,

electronics,

personal equipment.

As load increases, the product needs more than thicker shoulder straps.

Important elements may include:

• frame sheet or stay system;
• adjustable torso;
• load lifters;
• lumbar support;
• structured hip belt;
• stable shoulder anchors;
• lower reinforcement;
• compression zones.

A useful sample review should include several load conditions.

Load Condition	What to Check
30–40% full	Does the body collapse?
60–70% full	Does the load remain centered?
Intended full load	Does the hip belt carry meaningful weight?
Walking test	Does the pack sway?
Stairs or incline	Does the load shift vertically?
Compression tightened	Can partial loads be stabilized?

The hip belt is especially important.

If the pack is intended to carry 12–16kg or more, the belt should do more than wrap around the waist. It should work with the back structure and torso geometry so some of the weight moves away from the shoulders.

A thick, soft belt attached to a flexible body may feel comfortable during a short fitting yet offer poor support after several hours.

For a serious trekking line, comfort must be evaluated under realistic weight.

Expedition Backpacks

Expedition backpacks are intended for larger loads, extended trips, and bulky equipment. Around 65–90L or more is common, but the correct capacity depends heavily on the use case.

The main challenge is balancing strength against empty weight.

It is tempting to use the heaviest fabric, thickest foam, largest buckles, and maximum reinforcement everywhere. That can create a durable pack that is already unnecessarily heavy before anything is loaded.

A better approach is to identify high-stress areas and reinforce them selectively.

These often include:

• shoulder-strap anchors;
• frame connection areas;
• hip-belt junctions;
• haul handles;
• compression anchors;
• bottom panels;
• tool loops;
• front equipment zones.

The rest of the shell can then use a lighter specification where exposure is lower.

Expedition packs should also be evaluated for shipping volume.

Large padded belts, rigid frames, and thick back panels can increase carton size significantly. For a 2,000- or 5,000-piece order, even a small reduction in packed thickness can change total freight volume materially.

This is why packing geometry should be considered during development rather than after the goods are finished.

Mountaineering Backpacks

Mountaineering packs are often more technical than their capacity suggests.

A 40L alpine pack may require more development than a 50L hiking pack because it has to carry specialized equipment while staying compact and stable during climbing.

Common features may include:

• ice-tool attachment;
• rope retention;
• crampon storage;
• reinforced abrasion panels;
• removable components;
• narrow body shape;
• glove-friendly buckles;
• haul loops;
• streamlined compression;
• minimal snag areas.

The design priorities are different from trekking.

A trekking pack may favor bottle access, ventilation, hip-belt pockets, and organization. A mountaineering style may deliberately remove some of those details to reduce interference with arm movement, harnesses, and technical equipment.

The backpack should also remain stable as gear is removed throughout the day.

A partly empty alpine pack that collapses or lets equipment shift can be more problematic than a slightly heavier design with better compression.

Material zoning is useful here as well. Areas exposed to rock, tools, or crampons may need higher abrasion resistance, while lower-stress panels can remain lighter.

For a coordinated outdoor collection, the visual language can stay consistent across hiking, trekking, and mountaineering products, but the structure should change with the activity.

The key is not to make every backpack look equally technical. It is to make each one perform correctly for what it is expected to carry.

Which Hiking Backpack Type Is Best for Each Use?

The right hiking backpack is determined by trip duration, equipment volume, realistic carried weight, terrain, climate, and how much support the body needs. Capacity helps narrow the choice, but it should not decide the structure by itself. A 25L fast-hiking pack and a 25L camera-oriented trail pack may need very different shoulder straps, back support, reinforcement, and pocket layouts because their loads behave differently.

A practical selection starts with what the pack must carry and how that weight should sit on the body.

Use	Practical Capacity	Common Carried Weight*	Structure Priority
Short day hike	12–20L	3–6kg	Light back support
Full-day hike	20–30L	5–9kg	Ventilation + stability
Technical day hike	25–35L	6–10kg	Better compression + support
Overnight	30–45L	7–12kg	Hip support + firmer back
Multi-day trekking	45–65L	10–16kg	Frame + load transfer
Long trekking	55–75L	12–18kg	Adjustable suspension
Expedition	65–90L+	15kg+	Strong frame + reinforcement
Mountaineering	30–55L	Activity dependent	Stability + gear attachment

• Carried weight is a development reference rather than a guaranteed load rating. Final requirements depend on the construction and intended use.

Capacity by Trip Length

Trip duration is a useful starting guide because longer outings normally require more food, clothing, shelter, and sleep equipment.

For a warm-weather day hike, 15–20L may be enough for water, food, a shell, and essential gear. A full-day trip in colder conditions may need 25–30L because insulated clothing occupies substantial volume even when it is lightweight.

An overnight style often moves toward 30–45L. Once sleeping equipment, food, cookware, and extra clothing are added, the bag needs more than additional space; it usually needs stronger load control as well.

For multi-day trekking, 45–65L is a common working size. Larger 60–75L products make more sense when equipment is bulky, resupply is limited, or colder conditions require more clothing and sleep insulation.

The mistake is assuming that one extra day always means a fixed number of additional liters.

Consider two trips:

Trip	Clothing	Sleep System	Food	Likely Volume Need
2-day summer trip	Light	Compact	Low	Relatively low
1-day winter hike	Bulky	None	Low	Can still be high

For product development, the more reliable method is to prepare an intended packing list and physically load it into an early sample.

Load vs Pack Size

Capacity tells you how much space exists. Weight determines how much structural work the backpack must do.

This distinction is critical.

A 25L pack carrying a camera, three liters of water, dense equipment, and batteries may place more stress on the harness than a 40L pack filled mainly with insulated clothing.

That means two products with the same volume can require different:

shoulder foam,

webbing,

reinforcement,

back stiffness,

hip support,

hardware.

A useful development specification should therefore include both capacity and expected load.

Instead of:

“30L hiking backpack”

a more useful brief is:

“30L hiking backpack, intended carrying weight around 7–9kg, ventilated back, hydration compatible, two side bottle pockets, trekking-pole attachment.”

That immediately creates a much clearer structural direction.

Load also affects comfort expectations.

At 4–5kg, a simple foam back may be sufficient. Once the weight moves closer to 10–12kg, shoulder pressure, pack sway, and lower-back support become more noticeable. At still higher loads, frame design and hip-belt transfer become increasingly important.

A strong fabric does not solve weak load transfer. Strength has to continue through the shoulder anchors, internal support, lower structure, and belt attachment.

Frameless vs Internal Frame

Frameless construction is suitable when low weight, flexibility, and simple carrying are more important than heavy-load support.

An internal frame becomes more useful when the pack must keep its shape, control a denser load, or transfer part of the weight toward the hips.

The decision should be based on function rather than appearance.

Construction	Advantages	Limitations	Better For
Frameless	Light, flexible, packable	Lower load support	Day hiking, ultralight use
Foam + frame sheet	Moderate weight, better shape	Limited heavy-load control	Larger daypacks, overnight
Single stay	Improved vertical support	More parts and assembly	Mid-size trekking
Dual stays	Better heavy-load stability	Higher weight and cost	Trekking, expedition
Stay + frame sheet	Balanced stiffness	More complex construction	Technical trekking packs

A frameless 25L product can work very well if the expected load is light.

The same construction can feel unstable when enlarged to 45L and filled with dense equipment.

Internal support also influences packing and freight. A rigid stay or frame can prevent the backpack from folding as tightly inside the carton, increasing shipping volume.

That should be considered early, especially for large-volume orders.

Ultralight vs Load-Bearing Packs

Ultralight and load-bearing products are built around different priorities.

Ultralight development focuses on removing unnecessary mass. Load-bearing development accepts more structure when that structure improves stability and carrying comfort.

The conflict becomes obvious when comparing two packs of the same size.

Specification	Ultralight 30L	Load-Oriented 30L
Empty weight target	550–800g	900–1,300g
Intended load	5–8kg	8–12kg
Back structure	Minimal	More supportive
Foam	Reduced	More developed
Hardware	Lightweight	Higher strength margin
Reinforcement	Highly selective	More extensive

These figures are working examples, not universal standards.

A common mistake is asking for a pack that is extremely light but also expected to carry heavy loads comfortably. Both goals can sometimes be balanced, but the design must become more efficient.

Weight can be saved through:

lighter but stronger fabrics,

shorter zipper runs,

reduced lining,

smaller buckles,

fewer decorative layers,

targeted reinforcement.

Simply removing the back structure is usually the easiest way to reduce grams, but it can also remove the very support that the final use requires.

Hiking vs Trekking Backpacks

Hiking and trekking products may look similar, but their priorities begin to separate as trip duration and carried weight increase.

A hiking daypack often emphasizes:

low empty weight,

airflow,

easy bottle access,

hydration use,

quick-access pockets.

A trekking backpack needs to pay more attention to:

torso fit,

hip-belt transfer,

load lifters,

frame stiffness,

compression,

lower reinforcement,

sleep-system storage.

The difference becomes clear under load.

A 25L hiking bag may be comfortable with 5–7kg even with fairly simple support. A 55L trekking style carrying 12–15kg will expose any weakness in shoulder geometry, belt placement, or frame structure.

For a coordinated outdoor collection, it often makes sense to keep the same design language across both categories—similar fabrics, colors, logo placement, buckle family, and visual details—while allowing the internal construction to change.

That gives the collection a consistent identity without forcing the same support system onto every product.

Trekking vs Mountaineering Packs

Trekking packs are usually designed for long periods of walking with sustained loads.

Mountaineering packs must also allow freer upper-body movement and accommodate specialized equipment.

This changes the layout significantly.

A trekking style may include:

large side pockets,

hip-belt pockets,

multiple access points,

extensive organization,

more comfort padding.

A mountaineering style may instead use:

narrower body geometry,

cleaner side panels,

ice-tool attachments,

rope retention,

haul loops,

reinforced abrasion zones,

removable components.

Neither is more advanced by definition. They solve different problems.

A 45L trekking backpack can therefore be a poor choice for alpine use even though the capacity is correct.

One practical issue is snag control.

Straps, oversized pockets, loose webbing, and protruding buckles that are harmless on open trails can become frustrating around rock, climbing hardware, or dense terrain.

Mountaineering designs often benefit from fewer exterior elements and stronger compression.

How Much Capacity Is Needed?

The correct capacity should hold the intended equipment without forcing excessive external storage or leaving so much empty space that the load becomes difficult to stabilize.

Three methods can be used to confirm it.

Calculated volume

Useful during early design, especially when dimensions are already defined.

Reference comparison

Useful when replacing an existing style or building a larger or smaller version of a proven pack.

Physical loading

Usually the most revealing method.

A calculated 35L volume can feel smaller in real use because:

back curvature consumes space,

foam intrudes into the body,

a hydration reservoir uses internal room,

pocket shapes are difficult to fill completely,

tapered panels reduce usable volume.

A simple physical check can prevent many later revisions.

Load the sample with the actual type of equipment expected for the intended trip. Check whether the main opening is wide enough, whether the bottom is difficult to reach, and whether the filled shape still looks correct.

For a product family with 20L, 30L, and 40L sizes, the capacity differences should also feel meaningful in real use, not only appear different in the specification sheet.

When Is a Hip Belt Necessary?

A hip belt becomes valuable when the backpack is heavy enough that transferring part of the load away from the shoulders improves comfort and stability.

For a small daypack, a simple webbing waist strap may mainly reduce side-to-side movement.

For a trekking pack, the belt can become a structural part of the carrying system.

A functional hip belt depends on five elements:

1. torso length;
2. back-panel stiffness;
3. belt attachment;
4. padded wing shape;
5. tightening system.

If one of these is wrong, thicker foam will not fix the problem.

A useful fitting check is simple.

Load the backpack to the intended weight. Tighten the hip belt first. Then adjust the shoulder straps and load lifters.

If most of the weight still hangs from the shoulders and the belt merely touches the waist, the load-transfer system may need revision.

The belt should also be checked at the smallest and largest intended fit settings.

For one-size products, padded wings that are too long may prevent smaller users from tightening the belt properly. Wings that are too short may concentrate pressure on larger users.

Pocket placement matters too. A large hip-belt pocket can add useful storage, but if it makes the padded wing too rigid or interferes with arm swing, convenience has been added at the expense of comfort.

For trekking and expedition products, the belt should be treated as part of the suspension—not as an accessory attached after the main backpack has already been designed.

How Are Custom Hiking Backpacks Engineered?

A custom hiking backpack is engineered as a complete carrying system rather than a fabric shell with straps attached. Capacity, expected load, torso fit, shoulder geometry, hip support, back stiffness, ventilation, fabric strength, hardware, reinforcement and equipment attachments must work together. As volume and carried weight increase, structural support and load transfer become increasingly important, while every additional component also affects finished weight, sewing complexity and cost.

A useful development sequence is to define the intended use and carrying weight first, then decide how much support, padding and reinforcement the pack actually needs.

Development Area	Light Daypack	40–50L Hiking Pack	55–75L Trekking Pack
Back support	Foam / light sheet	Structured panel	Frame sheet / stays
Hip belt	Optional / stability	Moderate support	Load-transfer function
Shoulder padding	Light–medium	Medium	More structured
Compression	Limited	Usually useful	Important
Reinforcement	Key anchors	Multiple load zones	Extensive load zones
Fit control	Basic	More important	Critical
Empty-weight pressure	High	Balanced	Balanced against support

These are development references rather than fixed specifications. A dense 30L load can require more support than a lightly packed 45L bag.

Custom Suspension Systems

The suspension system controls how the load connects the backpack to the body. For a small daypack, this may involve shaped shoulder straps, a sternum strap and a moderately structured back. Larger trekking products can require a frame sheet, aluminum stays, load lifters, lumbar support and a functional hip belt.

The important part is the load path. Weight should move from the main body through the internal support and harness rather than hanging almost entirely from the shoulder seams.

Several dimensions deserve careful control during development:

• shoulder-strap anchor spacing;
• torso length;
• load-lifter position;
• belt height;
• lumbar location;
• shoulder-strap exit angle.

Even a 10–15 mm shift in a harness anchor can noticeably change how a pack sits.

For adjustable systems, testing should cover the shortest, middle and longest settings. A suspension that feels balanced only at one setting may become unstable at the adjustment limits.

Shoulder Strap Design

Shoulder straps must distribute pressure without becoming excessively bulky or hot.

Important variables include width, curve, foam density, foam thickness, mesh, binding construction and attachment angle. More foam is not automatically better. Very soft thick padding can compress rapidly under weight, while firmer layered foam may maintain support with less bulk.

The upper attachment area deserves particular attention because it repeatedly receives force when the pack is lifted and carried.

A useful prototype check includes:

• whether both straps sit symmetrically;
• whether the inner edges press against the neck;
• whether the strap twists after tightening;
• whether foam collapses under the intended load;
• whether webbing adjusters move smoothly.

For larger packs, shoulder straps should also work with the hip belt. If tightening the belt does not reduce some shoulder pressure, the overall suspension may need revision rather than simply adding more shoulder padding.

Hip Belt Construction

A trekking hip belt should do more than wrap comfortably around the waist. Its main function is to help transfer part of the load toward the pelvis.

Three areas determine performance:

attachment, padded wing geometry, and tightening hardware.

A thick belt connected to a flexible lower panel may feel substantial but carry little weight. A more moderate belt attached correctly to a stable lower structure can perform much better.

The padded wings should follow the body without folding sharply. Their usable length must also suit the intended fit group.

During sample testing, load the backpack and tighten the belt before fully tightening the shoulder straps. Then observe whether the pack remains supported when shoulder tension is slightly reduced.

Hip-belt pockets should be evaluated carefully too. Oversized pockets can add useful storage but may stiffen the belt or interfere with arm movement.

Back Panel Ventilation

Back ventilation can be created with shaped foam channels, spacer mesh, segmented pads or suspended mesh.

Each construction changes both airflow and load position.

Foam-channel backs keep the pack relatively close to the body. Suspended mesh creates a larger air gap but normally requires additional structural tension and may move the load farther away from the spine.

That distance matters because weight positioned farther from the body creates greater leverage.

For warmer-climate hiking products, evaluate:

• airflow channels;
• mesh tension;
• foam recovery;
• pressure concentration;
• deformation after loading.

The back panel should also be inspected after repeated compression in cartons because some foam or mesh structures may recover differently after long periods packed flat.

Good ventilation is therefore a balance between airflow, load control, durability and packed volume rather than simply using more mesh.

Frame and Support Systems

The internal support structure determines how well the body of the backpack maintains shape under load.

Common options may include foam, PE board, EVA, plastic frame sheets and metal stays, depending on the intended construction. Jundong’s documented material capability includes foam, EVA, PE board, padding and other structural materials used in custom soft-goods development.

A lightweight daypack may only need enough stiffness to prevent hard contents from pressing into the back.

A larger trekking style may need stronger vertical support so the upper body does not pull away from the wearer.

Support selection also affects freight. A rigid frame can limit how tightly the finished backpack can be folded, increasing carton volume.

For large orders, that difference can materially affect shipping cost, so frame decisions should be made before packing dimensions are finalized.

Fabrics and Coatings

One fabric specification should not automatically be used across the entire backpack.

Different areas face different stresses.

The bottom may need higher abrasion resistance. Side pockets may need stretch or mesh. The front body can prioritize appearance and lower weight. Internal lining needs clean construction and suitable tear resistance rather than the same outdoor exposure performance as the shell.

Jundong’s backpack material scope includes polyester, nylon, Oxford fabric, RPET, mesh, foam padding and lining fabrics.

Fabric selection should consider:

• weight;
• abrasion exposure;
• coating;
• tear behavior;
• hand feel;
• color consistency;
• logo compatibility.

Water-resistant fabric does not automatically create a waterproof backpack. Stitch holes, seams, zippers and openings remain possible water-entry locations.

If stronger weather protection is required, the entire construction should be reviewed rather than relying only on a coated outer fabric.

Eco-Friendly Material Options

Recycled polyester such as RPET can be considered for sustainability-focused backpack programs.

It can be used for shell panels, linings or selected components depending on the required performance. Jundong lists RPET as an available option for backpacks, while also requiring any GRS or related documentation to be confirmed according to the project and actual material source.

A serious material review should go beyond the word “recycled.”

Consider:

durability, coating, abrasion resistance, color consistency, repeat availability and documentation.

A material with recycled content that fails prematurely can create a worse overall product outcome than a carefully selected durable construction.

If certified recycled content is required, the certificate scope, material lot and paperwork should be checked before production rather than assumed after the goods are finished.

Zippers and Buckles

Zippers and buckles affect daily usability more than their size suggests.

Zipper selection can involve coil size, slider configuration, reverse or standard orientation, puller design and the amount of curve in the opening. A long curved zipper often experiences more tension than a short straight one.

Buckles should match webbing width and expected force.

During prototype review, operate every zipper under three conditions:

empty,

partly filled,

heavily packed.

A zipper that runs perfectly on an empty sample may bind when the fabric is under tension.

Buckles should also be tested with repeated opening and tightening. Larger hardware is not automatically better; unnecessary oversized components increase weight and can make the backpack look bulky.

The strongest component selection is the one that provides enough performance without adding unnecessary mass.

Webbing and Reinforcement

Webbing carries force through shoulder adjustments, hip belts, compression straps, haul handles, sternum systems and equipment attachments.

Its width, thickness, weave and surface finish influence strength and adjustability.

However, strong webbing does not help if it is sewn into a weak section of fabric.

High-stress anchors may require:

extra fabric layers,

larger reinforcement patches,

bartacks,

folded seams,

additional backing.

Jundong’s documented quality approach treats shoulder straps, handles, reinforcement and other stressed sewn areas as important inspection areas.

Reinforcement should also be selective.

Adding thick backing behind every strap can make the pack heavy and stiff. Better engineering identifies where the load actually concentrates and strengthens those locations while keeping lower-stress zones lighter.

Hydration System Design

Hydration compatibility should be developed from the reservoir pocket through to the drinking tube.

The internal sleeve must fit the intended bladder volume without excessive movement. The hanger should support the reservoir without distorting the upper panel.

The hose route then needs:

a suitable exit opening,

left or right routing,

shoulder retention,

enough length at different strap settings.

A filled reservoir should always be used during sample checking.

A 2L bladder adds about 2kg of water, which can change how the back panel behaves and reduce usable main-compartment space.

For styles sold without a reservoir, compatible bladder dimensions should still be documented.

This is particularly important for repeat orders because a small reduction in pocket height or hose-opening position can make the finished product less compatible even though the exterior appearance remains unchanged.

Compression Strap Layout

Compression straps stabilize the contents and keep weight closer to the body when the pack is not completely full.

Their position matters more than how many are added.

Poorly placed straps can block bottle pockets, cross zipper paths or distort the side panels.

For larger hiking and trekking styles, upper and lower compression zones are often more effective than placing several straps randomly along the body.

A practical prototype test is to load the backpack to roughly half capacity and tighten the compression system.

Check whether:

• the load moves closer to the back;
• the pack remains symmetrical;
• pockets are still accessible;
• fabric does not buckle excessively.

If compression only wrinkles the shell while the contents continue moving freely inside, the location or internal structure may need adjustment.

Trekking Pole Attachments

Trekking-pole storage should be secure but easy to use.

Common solutions combine a lower loop with an upper elastic retainer or integrate the poles into side-compression straps.

The attachment should accommodate different pole diameters without allowing hard tips to damage the fabric.

Placement also needs to work with bottle pockets.

A pole stored directly over the bottle opening may make water access inconvenient. Likewise, a strap positioned too close to the user’s arm may create interference while walking.

During sample evaluation, attach and remove the poles repeatedly while the pack is filled.

This reveals whether the system is practical in real use, not just visually correct.

For brands offering several hiking models, using a consistent pole-attachment language across the collection can also improve visual identity while keeping each pack structurally appropriate.

Rain Cover Integration

A rain cover can be integrated into a bottom or front pocket or packed separately inside the main compartment.

If it is built into the backpack, the storage area should not weaken a high-abrasion bottom panel.

The cover must fit the backpack fully loaded, not only the empty shell.

Other useful checks include:

• perimeter elastic tension;
• coverage around the hip belt;
• drainage from the storage pocket;
• ease of removal with wet hands;
• storage after the cover becomes wet.

A rain cover improves weather protection but should not be used to describe the backpack itself as fully waterproof.

For large-volume projects, the additional cover, storage pocket and sewing steps also affect material cost, assembly time and packed weight.

The decision should therefore be made during development rather than added after the final backpack sample has already been approved.

How Does the Custom Hiking Backpack Process Work?

A custom hiking backpack moves from design definition to material review, pattern development, prototype testing, revision, pre-production approval, bulk production, multi-stage inspection, packing and international delivery. For technical outdoor packs, the approved sample should verify not only appearance but also load behavior, suspension geometry, reinforcement, hardware, capacity and packing details before volume production begins.

The sequence matters because later decisions depend on earlier ones. Changing the frame after artwork is approved may shift logo placement. Increasing foam thickness can alter shoulder-strap dimensions and carton volume. Replacing fabric after the prototype may change stiffness, seam behavior and color matching.

A practical project timeline can look like this:

Stage	Main Work	Key Output
Project review	Use, size, load, features, quantity	Development direction
Material review	Fabric, mesh, foam, webbing, hardware	Material specification
Pattern work	Panels, harness, pockets, volume	First pattern set
Prototype	Full construction	Physical sample
Testing & revision	Fit, load, function, appearance	Revised sample
Approval	Materials, dimensions, branding, packing	Production standard
Bulk production	Cutting, sewing, assembly	Finished backpacks
QC	Materials to pre-shipment	Inspection records
Packing	Labels, SKU, cartons	Shipment-ready goods
Delivery	Courier, air, sea, rail	Final handover

Design Brief

The process should start with the intended use rather than a vague instruction such as “make a 40L hiking backpack.”

A useful brief includes:

• product type;
• target capacity;
• approximate dimensions;
• intended carrying weight;
• trip duration;
• exterior fabric direction;
• lining;
• back structure;
• shoulder and hip support;
• pocket layout;
• hydration compatibility;
• equipment attachments;
• logo artwork;
• colors;
• quantity;
• packing needs;
• destination;
• required delivery date.

For a trekking pack, the expected load is particularly useful. A 45L design intended for 7kg of light equipment should not automatically use the same suspension as a 45L style intended for 12–15kg.

If some details are still open, they can be identified early instead of being decided after sampling begins. Jundong’s development review normally checks product type, reference material, size or capacity, material direction, logo, quantity, packing, special functions and delivery requirements before moving further.

Tech Pack vs Reference Sample

A tech pack gives measurable information. A physical reference shows construction and proportion that drawings may not communicate clearly.

For more complex hiking styles, using both can reduce misunderstanding.

A tech pack may include:

dimensions,

panel drawings,

materials,

logo size,

hardware,

stitching details,

packing instructions.

A physical reference helps evaluate:

back curvature,

foam thickness,

strap feel,

pocket accessibility,

frame stiffness,

overall proportion.

Neither should be copied without review.

A reference backpack may contain patented construction, unavailable hardware or materials that do not fit the intended cost. A drawing may also specify something difficult to reproduce consistently in volume.

The stronger approach is to identify which characteristics must remain unchanged—fit, capacity, opening, suspension, visual proportion—and then rebuild the construction around the actual project requirements.

OEM vs ODM Development

OEM is suitable when the product specification is already well defined and the main task is turning approved technical information into a reliable sample and later production.

ODM is more useful when the project begins with a concept, artwork, rough dimensions or reference images and still needs structural development.

A hiking backpack often sits between these two approaches.

Even when a complete drawing exists, technical review may still be needed for:

• shoulder geometry;
• foam thickness;
• frame stiffness;
• reinforcement;
• zipper length;
• pocket accessibility;
• packing efficiency.

Jundong supports custom, private-label, OEM and ODM bag projects, with separate development, design, sample-room, production and inspection functions.

The important distinction is not the label attached to the project. It is whether every unresolved technical detail has been identified before materials are committed.

Material Review

Material review should happen before the first pattern is fully locked because fabric thickness, stiffness and stretch can change the final shape.

For a hiking backpack, the material list may include:

outer fabric,

reinforcement fabric,

lining,

mesh,

foam,

frame sheet,

webbing,

elastic,

zippers,

buckles.

Different zones may require different specifications.

The bottom might need higher abrasion resistance. Shoulder anchors may need stronger backing. Side pockets may use mesh or stretch fabric. The front body can remain lighter.

Color matching also deserves early attention. One backpack can combine nylon, mesh, zipper tape, webbing and buckles from several sources. “Black” from five components may not look identical under natural light.

Material hand feel, thickness, coating, color and logo effect should therefore be confirmed during sampling, not after bulk cutting has started.

Pattern Development

Pattern development turns the design into cuttable, sewable pieces.

For hiking backpacks, pattern accuracy affects more than shape. It determines usable capacity, shoulder-strap angle, pocket depth, zipper tension and how the pack sits against the body.

A few millimeters can matter at certain locations.

Examples include:

shoulder anchor spacing,

load-lifter position,

torso length,

hip-belt attachment,

hydration sleeve height.

The first pattern should be treated as a development version rather than the final production standard.

Once the first physical sample is filled and worn, panel curves or harness positions may need adjustment.

This is especially common when moving from 2D drawings to a structured 3D trekking pack. The body may look correct on a table but change significantly when loaded.

The approved pattern should eventually correspond with the final sample so later production is not based on an outdated version.

Prototype Sample

A prototype is where design assumptions become measurable.

For a technical hiking backpack, the sample should verify:

• exterior dimensions;
• real capacity;
• material feel;
• back structure;
• shoulder comfort;
• hip-belt position;
• pocket accessibility;
• zipper movement;
• hydration compatibility;
• logo placement;
• packing method.

Jundong’s standard sampling time is usually around 5–7 days, while selected simple styles may take approximately 2–3 days. More complex hiking structures, special materials or multiple revisions can require additional time.

A prototype should not be approved only because it looks attractive in photographs.

Put real weight inside it.

A sample stuffed with paper can hide poor load transfer, weak compression and unstable suspension.

Sample Testing

Testing should reproduce the intended use as closely as practical.

For a 20L daypack, this may mean several kilograms of water, clothing and trail gear. For a 55L trekking backpack, the load may be much higher.

Useful checks include:

Test	What to Observe
Loaded fit	Shoulder pressure and belt position
Walking	Side-to-side movement
Incline/stairs	Vertical load shift
Compression	Stability at partial volume
Zipper operation	Binding under tension
Bottle access	Reach while worn
Hydration	Reservoir and hose compatibility
Strap adjustment	Smoothness under load
Frame behavior	Collapse or excessive stiffness

Branding should also be checked with the pack filled. A front logo can appear centered when empty and visually shift once the front panel curves outward.

The same applies to embroidery, patches and reflective elements placed near seams or compression straps.

Sample Revision

Technical backpacks often require revision, and that should be treated as part of development rather than a failure.

Common changes include:

strap angle,

foam density,

frame stiffness,

pocket depth,

compression position,

zipper length,

logo scale,

color,

reinforcement.

The most efficient approach is to combine comments into one controlled revision list.

For example:

V1: back too flexible, bottle pocket too high, shoulder straps 15mm too close.

V2: frame adjusted, pocket lowered 20mm, shoulder spacing increased.

V3: approved except logo reduced from 85mm to 75mm.

This record prevents old comments from reappearing later.

Revision timing and cost depend on the amount of reconstruction, new materials and added tooling or setup. It should not be assumed that every revision is unlimited or free.

Pre-Production Approval

Before bulk production, all important details should be frozen.

The approval set may include:

• physical approved sample;
• measurement sheet;
• approved fabric;
• color reference;
• foam specification;
• webbing details;
• zipper and buckle references;
• logo artwork;
• label placement;
• packing instructions;
• carton marks.

For hiking backpacks, hidden structure should be documented separately where necessary.

An exterior sample does not reveal:

foam density,

reinforcement size,

internal frame material,

backing layers,

hidden bartacks.

These details matter for repeat production.

Once confirmed, the approved sample and production information become inspection references during bulk work.

Bulk Production

Bulk production usually includes material preparation, cutting, logo work, sewing, component assembly, in-process checks, finishing and packing.

For a simple hiking daypack, operations may be relatively straightforward.

A technical trekking product can involve far more steps:

multiple foam pieces,

frame sleeves,

reinforcement panels,

adjustable torso components,

large hip belts,

compression systems,

equipment loops.

Jundong’s regular bulk production time is usually 20–30 days. Actual timing can change with product structure, quantity, material availability, logo work, packing, production schedule and inspection requirements.

Material confirmation should therefore happen early when a fixed retail launch or warehouse delivery date exists.

Production time and international transit time should be calculated separately.

In-Process QC

Quality control should begin before the first finished backpack comes off the line.

Jundong has 80 QC inspectors, and inspection can cover incoming materials, cut parts, logos, sewing, function, finished goods, packing and pre-shipment checks.

For hiking backpacks, in-process checks can focus on:

shoulder-strap anchors,

frame installation,

hip-belt attachment,

bartacks,

zipper alignment,

pocket placement,

compression webbing,

back-panel symmetry.

Catching a wrong shoulder anchor during sewing is far less costly than discovering it after 2,000 backpacks are complete.

Inspection does not eliminate all variation, but it reduces the chance that one small error becomes a full-order problem.

Final Inspection

Finished goods should be checked against the approved sample and confirmed specifications.

Important items may include:

dimensions,

appearance,

color,

logo placement,

zipper function,

buckles,

straps,

pockets,

frame components,

packing.

For multi-SKU programs, color, quantity, barcode and carton accuracy deserve the same attention as sewing.

A technically good backpack placed in the wrong carton can still cause serious warehouse and retail problems.

Packing quantity, SKU labels and carton marks should therefore be part of final delivery quality rather than treated as separate administrative work.

Packing and Shipment

Packing should protect the backpack while controlling shipping volume.

Large trekking packs can become bulky because of:

thick hip belts,

foam backs,

frames,

large shoulder straps.

Before final cartons are ordered, it is useful to confirm:

units per carton,

folding method,

carton dimensions,

gross weight,

SKU separation.

International orders can be arranged through courier, air, sea, rail or an appointed forwarder according to quantity, deadline and destination.

EXW, FOB, CIF and selected DDP arrangements can also be reviewed case by case.

For larger-volume backpack programs, sea freight is often more economical, while air freight may be considered where timing is critical. Samples and urgent small shipments are commonly handled by courier.

A well-controlled project ends when the correct product, correct SKU, correct packing and correct shipping information all reach the same destination—not simply when the sewing is finished.

How Do You Choose the Best Hiking Backpack Manufacturer?

The best hiking backpack factory is not simply the one with the lowest quotation, the largest building, or the longest product catalog. A stronger choice is the facility that can translate a defined carrying requirement into a repeatable product—then maintain the same materials, suspension geometry, reinforcement, branding, packing, and quality standard across the full order.

For technical outdoor packs, selection should focus on relevant backpack experience, development capability, material sourcing, prototype control, load-bearing knowledge, production capacity, inspection depth, compliance support, order policy, lead time, and shipment coordination.

A practical evaluation can use a weighted score rather than relying on first impressions.

Evaluation Area	Suggested Weight	What to Verify
Outdoor backpack experience	15%	Comparable hiking and trekking styles
Product development	15%	Pattern, suspension, structure, revision ability
Sample-to-bulk control	15%	Approved sample converted into production standards
QC system	15%	Incoming, in-process, finished and packing checks
Material sourcing	10%	Fabric, foam, mesh, webbing, zippers, buckles
Load-bearing knowledge	10%	Shoulder anchors, frame, hip belt, reinforcement
Capacity and scheduling	8%	Staffing, lines, lead-time control
Compliance support	5%	Testing and documentation process
Packing and logistics	4%	SKU, labels, cartons, shipping terms
Commercial fit	3%	MOQ, pricing logic, communication

The percentage is only a working reference, but it helps prevent one attractive quotation from outweighing more important technical risks.

Outdoor Backpack Experience

Relevant experience matters more than generic backpack volume.

A factory may produce large quantities of school bags or laptop backpacks and still have limited experience with:

• adjustable torso systems;
• load lifters;
• structured hip belts;
• frame sheets;
• aluminum stays;
• hydration routing;
• trekking-pole attachments;
• technical compression systems.

Before moving forward, review several products close to the intended construction.

For a 55L trekking project, a useful reference is another load-bearing outdoor pack—not a 25L casual backpack made from similar nylon.

Physical samples reveal more than catalog photographs. Check the back structure, shoulder anchors, reinforcement, zipper installation, foam, hardware, and how the bag behaves when filled.

The closer the reference construction is to the planned product, the lower the development uncertainty.

Product Engineering Capability

A capable development team should be able to discuss what happens when one specification affects another.

For example:

If the empty-weight target is reduced by 200g, which components can safely be changed?

If the expected carrying weight increases from 8kg to 14kg, does the shoulder system need more reinforcement?

If the back panel becomes more ventilated, does the load move farther away from the body?

If thicker foam is added, will carton volume increase?

These are practical engineering decisions.

A good development discussion should cover:

load path,

torso length,

strap geometry,

foam density,

frame stiffness,

reinforcement,

access,

hardware,

packing efficiency.

Jundong’s established backpack scope includes capacity, compartments, shoulder straps, back padding, chest buckles, reflective details, load-bearing structure, and comfort-related development.

Factory vs Trading Company

A direct factory relationship can make technical communication easier because pattern development, sampling, production scheduling, and inspection are closer to the actual production floor.

The real issue, however, is transparency.

Confirm:

• where the sample is made;
• where patterns are developed;
• where bulk production takes place;
• who sources the main materials;
• who controls inspection;
• whether subcontracting is involved.

For a complex hiking program, hidden production transfers can increase variation.

A second facility may use a different foam density, sewing method, or reinforcement practice even when the outer appearance looks similar.

If production is split, the approved standards should be clear enough that each location follows the same construction and inspection references.

OEM and ODM Capability

OEM is suitable when the design is already technically complete.

ODM becomes useful when development is still open and the project needs assistance with structure, materials, compartments, suspension, or prototype refinement.

Many outdoor projects sit somewhere between the two.

Even a detailed tech pack can contain unresolved issues such as:

back stiffness,

foam thickness,

strap shape,

hardware substitution,

packing method.

Jundong supports custom, private-label, OEM, and ODM projects and has separate product development, design, sample-room, production, and inspection teams. Its facility includes more than 600 employees, approximately 18,000 m² of production area, and 80 QC inspectors.

A useful test is simple: send a partially developed brief and see whether the team identifies the missing technical details before quoting.

Material Sourcing Capability

A hiking backpack can contain ten or more material categories even before packaging is considered.

These may include:

outer fabric,

reinforcement fabric,

lining,

mesh,

foam,

webbing,

elastic,

zippers,

buckles,

structural board.

Material sourcing should therefore be judged by more than fabric availability.

Review:

• repeat availability;
• color consistency;
• minimum purchase quantities;
• replacement options;
• documentation where required;
• compatibility between components.

Jundong works with polyester, nylon, Oxford fabric, RPET, mesh, foam padding, lining fabrics, zippers, buckles, webbing, and structural materials used in custom bag development.

For repeated seasonal orders, consistency is especially important. A substitute buckle or coated fabric may change both appearance and performance.

Sample Development Team

The sample room is where drawings become a real product.

A capable team should be able to:

interpret references,

develop patterns,

build a complete prototype,

identify sewing difficulties,

implement revisions accurately.

For technical hiking packs, the first sample should expose structural problems before large quantities of material are cut.

Typical revision areas include:

shoulder spacing,

foam density,

frame stiffness,

pocket depth,

zipper path,

logo placement,

compression position.

Jundong’s standard sampling time is usually 5–7 days, while selected simple styles may take about 2–3 days. Complex structures, special materials, or further revisions can require additional time.

The more complex the suspension system, the more valuable a disciplined revision process becomes.

Load-Bearing Experience

Load-bearing knowledge should be visible in the construction.

Inspect:

• shoulder-strap anchors;
• bartacks;
• reinforcement patches;
• frame attachment;
• hip-belt connection;
• haul handles;
• compression anchors;
• lower panel structure.

Strong fabric alone does not create a strong backpack.

The force has to travel through several connected parts without concentrating at one weak seam.

For a serious trekking project, provide a realistic carrying-weight target from the beginning.

For example:

55L pack, intended loaded weight approximately 12–15kg.

That figure gives the development team something concrete to work around.

A sample should then be loaded to the intended working weight and checked for sagging, strap distortion, belt performance, and body sway.

Factory Scale and Capacity

Capacity becomes more important when the program includes several colors, multiple SKUs, repeat orders, or fixed seasonal deliveries.

Jundong has more than 600 employees, approximately 18,000 m² of production space, and 80 QC inspectors.

Scale should still be evaluated together with control.

Useful operational checks include:

• how many styles can run simultaneously;
• whether SKU separation is controlled;
• how materials are staged;
• how in-process defects are corrected;
• how production status is communicated.

A large facility without clear control can still create inconsistent results.

The objective is not simply high output. It is stable repeatability.

Sample-to-Bulk Control

This is one of the most important areas to evaluate.

The approved prototype should become the reference for:

measurements,

materials,

colors,

logo position,

foam,

hardware,

reinforcement,

packing.

Jundong uses approved samples and confirmed production details as references during bulk production and inspection.

For technical backpacks, hidden components should also be recorded.

An exterior sample does not show:

frame material,

foam density,

backing layers,

internal bartacks,

reinforcement size.

If those details are not documented, repeat orders can gradually drift.

QC and Testing Systems

Final inspection alone is not enough for a complex backpack.

A stronger system checks quality throughout the production flow.

Jundong has 80 QC inspectors, with checks that can cover incoming materials, cut pieces, logo work, sewing, function, finished goods, packing, and pre-shipment inspection.

For hiking backpacks, inspection should pay particular attention to:

shoulder anchors,

webbing strength,

frame installation,

zipper movement,

symmetry,

pocket location,

back padding,

buckles,

dimensions.

Where testing is needed, requirements should be confirmed according to the product, materials, destination, and intended use.

No quality system should be described as guaranteeing zero defects. The purpose is to detect variation early and reduce the chance that a small issue spreads through a large order.

Social Compliance Audits

For projects that require social-responsibility documentation, current audit reports should be verified directly.

Check:

audit program,

facility name,

address,

audit date,

validity,

corrective-action status.

Do not rely only on logos shown on a website or presentation.

Jundong’s factual rules specifically prohibit claiming BSCI or other certificates without valid supporting documents.

The safest approach is to review the document that applies to the actual production facility before qualification.

Compliance and Testing Support

Testing requirements depend on the product, materials, destination, labels, and intended use.

A standard adult hiking pack may have different requirements from a children’s style or a product making specialized performance claims.

Jundong can coordinate third-party testing and review supporting documents according to project requirements, but specific certification claims should only be made when real supporting records exist.

This is also why testing should be discussed before the quotation is finalized.

Testing can affect:

sample timing,

production scheduling,

cost,

shipment date.

MOQ for Custom Backpacks

Jundong’s standard MOQ is usually 500 pieces per design.

Selected simple styles may be reviewed at 200–300 pieces, while some low-unit-price basic products can require 1,000 pieces or more.

MOQ is connected to:

material purchasing,

color setup,

logo preparation,

cutting,

sewing,

packing,

QC,

production scheduling.

For multi-color hiking programs, quantity per color can matter as much as total quantity.

A 2,000-piece order divided into eight colors may be more complicated to source than the same quantity divided into two colors.

Backpack Price

Price should be compared only when the specifications are aligned.

Major cost drivers include:

material,

size,

structure,

foam,

frame,

zippers,

webbing,

hardware,

logo method,

packing,

quantity,

testing,

delivery timing.

A simple 35L hiking bag and a 35L style with an adjustable torso, suspended back, structured hip belt, custom hardware, rain cover, and multiple compression zones are not comparable simply because their capacity is the same.

Jundong’s pricing logic is based on project requirements rather than lowest-price claims.

Bulk Lead Time

Jundong’s regular bulk production time is usually 20–30 days after the main specifications and materials are confirmed.

Actual timing depends on product structure, quantity, material availability, logo work, packing, production schedule, inspection, and shipping method.

For a launch calendar, production and transit should be planned separately.

A realistic schedule should include:

sample,

revision,

approval,

material preparation,

production,

inspection,

shipping.

Shipping Terms

Common shipment options include courier, air freight, sea freight, rail freight, and an appointed forwarder.

Trade terms such as EXW, FOB, CIF, and selected DDP arrangements can be reviewed according to the project. DDP should not be assumed for every destination.

For larger backpack orders, sea freight is often the more economical choice because padded and framed products can occupy substantial carton volume.

Before comparing freight, confirm:

carton size,

gross weight,

quantity per carton,

destination.

Accurate shipping cost cannot be calculated from product unit weight alone.

Quote Preparation

A useful RFQ should include enough detail to make the quotation technically comparable.

Send:

• reference image or drawing;
• capacity;
• exterior dimensions;
• intended use;
• expected load;
• material preference;
• logo;
• quantity;
• color count;
• packing;
• destination;
• delivery date.

If some details are not final, state which ones are open.

That allows material and structure options to be reviewed before the price is fixed.

Jundong can assess the project after receiving the main specifications and can suggest material or construction directions where required. For a detailed review, information can be sent to info@jundongfactory.com.
