Waterproof: Constructed with 100% waterproof materials to deliver protection in waterlogged environments. Easy gear retrieval: Clear body fabric allows viewing of contents within, making quick gear retrieval a cinch. Heavy-duty: Rugged materials stand up to heavy use on both water and land. Durably constructed: Fully welded seams result in stronger and more durably waterproof construction compared to sewn-and-taped seams. Confident roll-top closure: Our original DrySeal closure design amplifies waterproof protection. PVC-Free: Materials have a reduced environmental impact over vinyl-coated materials.
