The Native Ultimate 14.5 Stern Bag is a great addition to any kayak, but was specially created to fit in the stern of the Ultimate™ 14.5 Tunnel Hull. The Native Ultimate 14.5 Stern Bag is insulated and waterproof up to the non-corrosive nylon coil zippers around the top so it serves as a great cooler for any outdoor function. The dual compartments help keep the contents organized and secure.
