What Sea to Summit says
Big River Dry Bag The Big River Dry Bag is a durable, abrasion-resistant waterproof storage bag designed for kayaking, canoeing, rafting, bikepacking, motorcycle touring, and overland travel. Constructed from rugged 420D nylon with a TPU laminate, it keeps gear dry while providing secure attachment points for kayaks, bikes, motorcycles, and 4WDs. A waterproof roll-top closure, reinforced seam construction, and abrasion-resistant base deliver reliable protection in demanding outdoor environments.
