Hide your camera, phone or a towel in this waterproof bag. Transport wet gear in a car trunk, or inside a backpack, full of dry clothes without concern. Store food and clothes safely in a kayak without getting any moisture on them. Use as a pillow. Fill with ice and bring it to a beach party, or carry it alone as a waterproof backpack. It can act as a waterproof phone pouch, or secure storage area for your camera. You get the idea. 
ATTENTION: to make sure the bag is properly closed align the edges properly and at minimum three times before snapping the buckle. Squeeze the bag - if there is air coming out the chances are water will get in.
