The Big River Dry Bags are a durable, strong and abrasion resistant option that uses a 420D nylon fabric with a TPU lamination. If your idea of outdoor recreation involves rugged water sports like kayaking, canoeing, rafting, or motorcycle touring, these are the perfect storage bags to keep your gear dry. A white interior laminate affords greater visibility, and hypalon lash loops allow secure stacking or attachment to watercraft, motorcycles and other equipment. The hypalon roll-top closure does not wick water, and the Field Repair Buckles can be replaced in seconds with just a Philips screwdriver.
