Best Coolers for Camping and Outdoor Use

We reviewed hard-sided coolers across ice retention, wall insulation thickness, latching system, drain plug design, and weight for their capacity. The picks cover sizes from 32-quart day-trip coolers to 72-quart family-size wheeled units.

Ice retention is the spec most coolers advertise but few explain. Rotomolded construction and thick foam walls are the two variables that matter most. Rotomolded coolers are made from a single piece of plastic with no seams, which eliminates the gaps where heat enters. Injection-molded coolers (the cheaper construction method) have seams that allow heat transfer and eventually crack under heavy use. RTIC's Ultra-Light line uses a non-rotomolded construction that achieves competitive ice retention at meaningfully lower weight, which is a genuine innovation in the category.

Size selection involves a common miscalculation: buyers estimate volume by drinks and forget ice. A 52-quart cooler holding 52 quarts of beverages sounds enormous, but ice-to-beverage ratio for adequate cold retention should be roughly 2:1 (two parts ice to one part drink) for day trips and up to 3:1 for multi-day camping. That 52-quart cooler realistically holds about 17 quarts of beverages when properly iced for a two-day trip. Factor in your actual contents before choosing a size.
