Centered on a 17.5 in interior with 37 quarts of chilled space, this hard shell ice chest delivers 3-day ice retention through triple-wall insulation. Light enough to carry on day trips yet sturdy enough for boat decks and campsites, the unit ships with 2 lid cup holders, a fish measuring ruler, and a built-in bottle opener. Safety buckles, a sealing ring, and a leak-proof drain plug keep contents secured during transport.
