This weatherproof bag combines the convenient access and storage capacity of a large duffel with the water resistance and ruggedness of our most durable dry bags. Utilizing the time-tested, 3-way roll-down closure system and constructed of super tough tarpaulin material, the Mariner Duffel is our most versatile pack offering yet. Every inch of this heavy-duty, top loading gear bag is heat welded and bound to prevent water intrusion during any aquatic activity. In addition to the rugged 2" webbing, beefy d-rings, daisy chains, and sealed zippers, this pack includes two detachable, adjustable, molded backpack straps for quick conversion to a hands free cargo hold. Measures: 12"W x 24"L x 12"H (22"H when open)
