The Big River Dry Bag is designed for extended expeditions and touring. Its TPU-laminated construction with full seam sealing ensures waterproofing. The 420-denier nylon shell resists abrasion from rocks and rough handling. The roll-top closure compresses contents while sealing out moisture. Multiple lash points allow secure attachment. Its 10K waterproof rating can withstand full submersion. This dry bag protects electronics, clothing, and critical gear during paddling, motorcycle touring, and wilderness camping.
