Engel Coolers’ ENG65 hard cooler and ice box is the industry’s first ever roto-molded high-performance cooler. Its rotationally molded construction provides a seamless finish and makes it one of the most durable coolers on the market. So durable in fact that the Interagency Bear Committee (US Dept. of Forestry) has approved this cooler as “bear resistant” when used with two padlocks or when bolted shut in both corners (molded on the rear side of the coolers lid). With its 2-inch, 360 degrees, closed cell foam insulation, and heavy-duty silicone gasket, the Engel high-performance hard cooler and ice box has the ability to retain ice for up to eight days in ideal conditions. Unlike its competition, this cooler has interchangeable, adjustable rubber and stainless-steel latches depending on your preference. Both latch options are compatible with the standard stainless-steel upper latch keeper that duals as an emergency bottle opener… yes, we thought of everything. This cooler boasts a myriad of other innovative features like its non-skid, non-marking cornerstone feet, built-in durable rope handles with ergonomic plastic hand grips for comfort, a pitched cooler floor with an extra-large large removeable drain plug for optimal self-drainage, and quadra-grip tie down points to easily secure your cooler.
