Simply put, Dorsal Tuff-Tote Coolers are the best soft-sided coolers on the market. We start with the toughest 1800D nylon, and combine that with a rugged hard shell, yet flexible base. Superior insulation is provided by our Thermo-reflective material that enable Dorsal Tuff-Tote coolers to stay cold for hours. Unlike other soft coolers, we integrate a replaceable waterproof liner that assures there will be NO leaks. They have a side pocket for your valuables as well as a “daisy chain” loop system on the outside for external storage capabilities. The Tuff-Tote cooler comes in three sizes to accommodate anything from an afternoon on the boat to a weekend of camping. These features, along with Dorsal’s lifetime warranty, assure you cannot make a better decision when purchasing a soft cooler. The Medium Cooler is the perfect size for an all day trip to the beach or pool with plenty room to pack for several people . Measurments are: 24″ x 16″ x 10″
