Sea to Summit Big River Dry Bag

The Big River Dry Bag is a waterproof roll-top made from abrasion-resistant 420D nylon with a TPU laminate, tougher than Sea to Summit's lighter stuff sacks and built for repeated contact with rock, gravel or a boat deck. Lash points let you strap it to a kayak, raft, bike or motorcycle rather than just stuffing it inside a pack. It's aimed at water sports and bikepacking or moto touring rather than backpacking, where the weight and bulk of the tougher fabric would be unnecessary compared with a lighter dry bag or stuff sack.
