This bag is a great addition to any kayak, but was specially created to fit in the bow of the Ultimate 12 Tunnel Hull. It is insulated and waterproof up to the non-corrosive nylon coil zippers around the top so it serves as a great cooler or gear bag for any outdoor function. The bungee cord on the top lets you attach a tackle box or other gear on top or secure the bag to your kayak. It's easy to transport with side carry handles and a removable shoulder strap.
This is a great bag, I use it to store lunch and drinks or I use it to store clothes and other gear. It also works well for a place to secure my paddle while fishing.
Great bag lots of space and well insulated, well worth the money. You can actually use it with the bow skirt in place so that it's tucked away under the skirt.
