This mid-size dry bag is the ideal carrier to transport your gear and protect it from water, sand and dust while out on diving tours or other outdoor activities. The backpack-style bag is 100% dry, thanks to a super-tough fabric blend ? 85% 500D nylon and 15% polyester backed by a TPU coating. The roll-and-close system is super-easy to use, and an outside zippered pocket keeps smaller items accessible. A comfortable padded backpack system makes for effortless gear hauling.
