Ultratherm insulation keeps water, food, beverages, or medical supplies cool and withstands tough job conditions or repeated use such as medical transport. Can be secured by handles to the bed of a truck for safe transport. The insulated body keeps contents cold longer, uv inhibitors guard against sun damage, and the stain and odor resistant liner stays clean and odor free. Reinforced swing up handles with tie-down feature. All stainless steel screws.
