Free Sample OEM waterproof backpack for kayaking with 20L PVC tarpaulin body, roll-top closure, removable shoulder strap, screen print logo, and custom color options for outdoor and water sports buyers
Product Overview & Customization Capabilities
This waterproof backpack for kayaking is built for outdoor camping, hiking, travelling, boating, beach storage, fishing, and wet gear transport. The bag uses PVC tarpaulin material with a roll-top closure structure to help protect clothing, towels, electronics, shoes, and personal items from rain, splashes, mud, and wet ground contact.
The standard capacity is 20L, with a listed size of 23 × 16 × 60 cm and an approximate weight of 0.6 kg. The softback body uses moderate hardness, allowing the bag to remain packable while keeping enough structure for outdoor carrying.
The roll-top opening allows users to fold the upper section before fastening, which is a common structure for dry bag backpacks used in kayaking, camping, hiking, and travel. The shoulder strap is removable, supporting different packing, carrying, and retail display needs.
For OEM and wholesale orders, Xiamen Topmatched supports customized color, custom dimension, screen printing logo, label, hangtag, packing method, carton mark, and mixed outdoor bag programs. MOQ starts from 500 pcs, suitable for outdoor gear brands, kayaking equipment distributors, camping product importers, travel goods wholesalers, and private label retail programs.

Waterproof Performance Notes
This product is designed as a roll-top waterproof backpack for outdoor splash, rain, wet ground, kayaking, camping, and travel use. Buyers should define the required waterproof level before production. If the target market requires submersion resistance, a separate water pressure, air leakage, or immersion test should be requested during sample approval.
For standard kayaking and outdoor retail programs, the approved sample should confirm PVC tarpaulin thickness, seam sealing method, roll-top folding count, buckle quality, strap strength, and printed logo durability.

FAQ
How should buyers test the roll-top waterproof structure before bulk production?
Buyers should confirm PVC tarpaulin quality, seam sealing method, buckle strength, folding count, and strap connection on the approved sample. For kayaking retail programs, request a splash test or short-duration water exposure test based on the final use environment.
Can the waterproof backpack be customized with logo and brand colors?
Yes. Screen printing is the standard logo method, and custom colors are available for OEM orders. Buyers should approve logo artwork, print size, print position, color sample, and packing layout before mass production to reduce batch variation.
Is this 20L waterproof backpack suitable for kayaking and camping?
Yes, it is suitable for kayaking, camping, hiking, travelling, fishing, and beach use when used for rain, splash, and wet gear protection. If the product must resist full submersion, buyers should request additional immersion or air leakage testing.
