The Big River Dry Bag features abrasion-resistant 420-denier nylon laminated with TPU for strength and waterproofing. It has double-stitched, tape-sealed seams and a waterproof roll-top closure. The white interior improves visibility, while low-profile grab handles reduce snagging. An oval base prevents rolling and aids packing. Multiple lash points allow mounting on kayaks, bikes, motorbikes, or 4WDs. The bag is PFC-free and not intended for prolonged submersion.
