Spec snapshot
A fast engineering view of what matters for sourcing, quoting, and repeatable production.
| Item | Typical | Notes |
|---|---|---|
| Protection target | packing + splash / higher waterproof (by spec) | Dry sacks vary widely; define target use to choose seam strategy |
| Seam build | stitched + taped / welded (by spec) | Stitched sacks can still be very effective for packing; welded for higher targets |
| Compression option | compression straps (by spec) | Used for sleeping bags; requires reinforced strap anchors |
| Base shape | round / oval / flat base (by spec) | Oval packs better in backpacks; round is most common |
| Typical MOQ | 500–1500 pcs | Depends on fabric, printing, and whether seams are taped |
Roll-top closure usage rules
Roll-top performance depends on user behavior and spec clarity. These rules improve real-world sealing and reduce returns.
| Rule | Why | Control |
|---|---|---|
| Minimum roll count | roll-top seals only after enough folds | define 3 folds minimum and buckle alignment in the tech pack |
| Overfill control | overfilling reduces roll depth and causes seepage | mark max fill line and validate with a packed sample |
| Buckle orientation | wrong buckle direction twists the seal | standardize buckle direction in production and QC photo gate |
| Handle loop placement | users carry by loops; weak loops fail first | reinforced bartack and pull check on loop stitching |
Dry sack seam strategy
Dry sacks range from packing organizers to higher-protection gear. Seam strategy must match the claim level and target use.
| Method | Water level | Best for | Tradeoff | QC gate |
|---|---|---|---|---|
| Stitched seams (no tape) | packing + splash | ultralight backpacking organization | not for immersion | seam allowance and needle spec control |
| Stitched + seam tape (by spec) | higher water resistance | wet climates and boat storage | more process steps | tape adhesion checks and corner sealing review |
| Welded seams (by spec) | waterproof construction | higher performance programs | material and tooling constraints | weld parameter records and peel checks (by spec) |
Compression dry sack design
Compression sacks need strap engineering and abrasion controls. These design choices keep ultralight fabrics from failing at anchor points.
| Feature | Options | Risk | Control |
|---|---|---|---|
| Compression strap layout | 2-strap / 4-strap / cross (by spec) | strap tear-out on light fabrics | reinforcement patch and stitch map approval |
| Base reinforcement | double-layer base / skid panel | abrasion through at campsite floors | abrasion checks (by spec) and visual gate on edge binding |
| Air purge (optional) | one-way valve (by spec) | leak path and returns if misused | instruction insert + valve QC sampling |
| Set packaging | mesh bag / band wrap / box | mixed sizes in carton | size label system and packing list reconciliation |
Water ingress test plan
Claims should match validation. We align a practical test plan to your target use (packing/splash vs higher protection by spec).
| Test | Setup | Pass criteria | Notes |
|---|---|---|---|
| Spray test | simulated rain spray for 2–5 minutes | no visible water inside for defined target | best for packing/splash positioning |
| Quick dunk (by spec) | submerge for 10–30 seconds | limited/no ingress based on program target | requires defined roll count and closure method |
| Seam tape peel check (by spec) | manual peel + heat aging sampling | no delamination within agreed range | important for taped seam programs |
Capacity & dimensions reference
Standard size options for dry sacks. We can also customize dimensions to fit your specific gear.
| Volume | Typical Dimensions | Best For |
|---|---|---|
| 5L | ø18×35cm (typical) | essentials and small electronics protection |
| 10L–15L | ø20×45cm / ø24×50cm | clothing kit and day-hike packing |
| 20L–30L | ø28×55cm / ø30×60cm | sleeping gear and camp organization |
| Set pack | 5L+10L+20L (typical) | multi-size retail sets and travel organization |
Materials & fabrics
Material choice drives performance, durability, finishing, and target price point.
| Fabric | Waterproof | Cost | Notes |
|---|---|---|---|
| 70D–210D nylon + PU/TPU coating | water-resistant to waterproof | varies | Lightweight choice; performance depends on seam/closure spec. |
| Ripstop polyester + coating | water-resistant | varies | Stable hand-feel and printability for branded programs. |
| TPU laminated fabric | waterproof (by construction) | varies | Higher waterproof performance when paired with sealed seams. |
Manufacturing & QC process
1
Size Set & Pattern Lock
Confirm volume range, base shape, and roll-top geometry to avoid fit issues in sets.
2
Material & Seam Strategy
Select coated nylon or TPU laminate and decide stitched/taped/welded seam route by target protection.
3
Assembly & Reinforcement
Sew or weld panels, reinforce strap anchors, and control buckle alignment.
4
Seal Behavior Validation
Verify roll count behavior and run sampling tests (spray/dunk) aligned to claims.
5
Packout & Labeling
Execute set-based packing lists and apply size labels to prevent SKU mix-ups.
Quality & testing
• closure function check
• water ingress sampling test
• stitch strength spot checks
• AQL final inspection for shipment

Frequently asked questions
Q: Is a dry sack the same as a dry bag?
A: Dry sacks are often lighter and designed for packing organization and splash protection. For full waterproof performance, the construction and seam strategy must be specified clearly.
Q: Can you provide a set of multiple sizes in one pack?
A: Yes. We can produce multi-size sets and align retail packaging, inserts, and barcode labels.
Q: Can you add compression straps?
A: Yes. Compression straps can reduce volume for sleeping bags and bulky clothing, and we can reinforce the stitch points for long-term durability.
