Keep your items safe and dry while paddling. Available in different colors, these are a great addition to your board, and are extremely handy to have. Each bag features a watertight zipper pocket on the outside of the bag. We never go paddling without ours - in fact mine stays in my car 24/7! This is a 15 liter bag, which we feel is the perfect size - not too bulky yet not too small. Keep a little bit of air in the bag so it floats if it falls off. Comes with a removable shoulder strap. Made with heavy duty, vinyl-coated fabric for watertight protection.
