Four-day ice retention comes from a PE shell with PU insulation that slows heat transfer so drinks and food stay cold on extended outings. The 16 quart interior, measuring 12 x 9.5 x 10 in, holds up to 24 cans without ice, giving room to organize supplies for camping, picnics, or road trips. Reinforced locking latches help keep the lid secure, while a drain plug at the base lets you empty meltwater without lifting the cooler. Two molded cup holders on the lid keep drinks stable when the cooler is set down.
