A Roll-Top Seal That Floats Your Gear
With a correctly folded 3-5 fold roll-top, this backpack seals out rain, spray and splash, and the trapped air makes it float if it falls in the water. Welded seams mean there are no needle holes, eliminating the two most common leak points in waterproof packs.
Ready for Fishing, Boating, Rafting and Trekking
Built for waterside activity, this dry-pack carries your gear hands-free and keeps it dry through fishing, boating, rafting and trekking. Outdoor safety guidance recommends stowing gear in sealed, floatation-capable dry bags for paddlers and anglers, and this backpack is designed for exactly that use.

Frequently Asked Questions
Will this backpack float if I drop it in water?
Yes. With the roll-top sealed (3-5 folds), the air trapped inside makes the backpack float, so it is easy to retrieve while fishing, kayaking or rafting. (Source: JUNYUAN Bags OEM/ODM)
How waterproof is it compared to a normal backpack?
A normal backpack uses water-resistant fabric and stitched seams that leak quickly, while this model uses welded PVC with no needle holes and a roll-top seal that handles rain, waves and brief immersion. (Source: JUNYUAN Bags OEM/ODM)
What sizes and colours are available?
It is offered in two sizes and four standard colours to suit different outdoor programmes, with custom Pantone colours available for OEM orders. (Source: JUNYUAN Bags OEM/ODM)
What logo and customisation methods do you offer?
Screen printing, heat transfer, embroidery, rubber/TPU logos and woven labels, plus custom straps, buckles, hangtags and retail packaging, with artwork mock-ups before sampling. (Source: JUNYUAN Bags OEM/ODM)
How should I close the roll-top for maximum dryness?
Leave some air inside, fold the reinforced top 3-5 times, buckle and tighten. Keep the closure above the waterline and do not overfill past the stiffened band. (Source: JUNYUAN Bags OEM/ODM)
What is the MOQ and production timeline?
The MOQ is 500 pieces per design, pre-production samples take 6-10 days and mass production runs 35-50 days, with AQL 2.5 quality control and a 12-month warranty. (Source: JUNYUAN Bags OEM/ODM)
Is the roll-top backpack good for commuting too?
Yes. In addition to waterside use, it makes a dependable rainy-day commuting bag that keeps a laptop and documents dry. (Source: JUNYUAN Bags OEM/ODM)
How long do welded seams last?
Because welded seams have no needle holes, the seal lasts the life of the bag, unlike coated stitched fabric whose coating wears over time. (Source: JUNYUAN Bags OEM/ODM)
