Sea to Summit Big River Dry Bag 35L – Red/Orange Waterproof Dry Sack
Product Description
The Sea to Summit Big River Dry Bag 35L is a durable, abrasion-resistant dry bag designed to help protect your equipment during kayaking, canoeing, rafting, motorcycle touring, bikepacking and other outdoor adventures. Made from lightweight, waterproof TPU-coated 420D nylon, it combines rugged construction with a streamlined shape to provide dependable dry storage for essential gear.
Featuring a 10,000mm hydrostatic head rating, the fabric offers a high level of water resistance. Reinforced seams are double-stitched and tape-sealed, while the waterproof Hypalon roll-top closure helps prevent water from entering through the opening. Durable Hypalon lash loops allow the bag to be attached to watercraft, secured to equipment or stacked with other bags.
The low-profile design helps save space, and the oval base helps prevent the bag from rolling around. A white interior lining improves visibility, making it easier to locate items inside. With a 35-litre capacity when the closure is rolled three times, this dry bag provides practical storage for paddle sports equipment, overnight camping gear and bikepacking essentials.
