The AO Stow-N-Go Cooler was designed to be easier to store on your boat. It is shallow, so you can fit it in most ski compartments or under seats. The HD model offers four D-ring tie down hooks and a foam molded bottom. The sleek Carbon Series is made with a vinyl coated fabric that looks like carbon fiber, which is widely used in both the RV and marine industries. It is insulated with a 3/4-inch thick closed cell foam to keep drinks and food cold for the weekend. It is lined with eco-friendly, leak proof, welded TPU.
