What makes the Dock & Bay waterproof Dry Bag so good? It's easy to use; just slip your valuables inside, roll & clip top closure to protect your items from water, sand, dust and dirt. Plus, it boasts a waterproof IP rating of IP66. Watertight welded seams will keep your dry items safe from the wet. Includes two interchangeable straps to wear as either a backpack or remove one strap to create a crossbody bag. Made from lightweight, recycled polyester & recycled polyurethane; no regular plastic here, just super durable, non-rip 420D fabric!
