Outfitted with YKK waterproof zippers and RF welded from double-coated (PVC-free) polyurethane, this commercial grade ‘made in the USA’ duffel is truly waterproof – Submersible to 15 feet! (making it class 5 waterproof) the wide 1.5 inch nylon webbing handles were designed to be long enough to use as backpack straps, should the need arise. And the 4 deluxe d-rings are perfect for securing the duffel in almost any situation. Compared in similar thickness polyurethane is superior to PVC most every way: cold weather, Direct sunlight, chemical resistance, crack resistance, abrasion resistance, environmental friendliness, and overall strength. And we chose some of the thickest double-coated polyurethane to maximize all of these positive characteristics. And not only is our bag manufactured in the USA, the YKK zipper we use is now also manufactured in the USA – also in the state of Georgia, in fact.
