Heavy-duty vinyl separates our coolers from the rest of the pack. Frost Paks are engineered for higher thermal efficiency and a longer life span than regular soft-sided coolers. Our expedition proven coolers feature a waterproof liner that prevents ice melt from penetrating insulation and are waterproof up to the zipper. Our 12 quart cooler and 19 quart cooler are the perfect size for day excursions and hikes. The 25-quart is sized to easily fit into automobiles and boats. The shorter in height and longer in length size of our 40 quart makes it a great cooler for rafts and canoes and can easily be lashed down. Dimensions: 20" L. X 11" W. X 7.25" H. Weight: 19 ounces
