At 8.5 pounds empty and 18.5 by 13 by 13 inches, this is the size of cooler that gets carried rather than left behind, and triple-layer insulation still delivers ice retention of up to 3 days. The 21-quart interior measures 14.5 by 9 by 10 inches, spacious enough for drinks, food and other items on a day out without the bulk of a full-size chest. Lightweight construction is the point here: mobility outdoors improves when the empty weight is low, because most of what is carried should be contents rather than shell. The material is PP, PU and ABS, and the lid is rated to 110 pounds, the same as the internal capacity, so it can be sat on or used as a surface once closed. Two cup holders are moulded into the lid to keep open drinks level, a bottle opener is built into the body, and a fish measuring ruler runs along the top with a scale ready when it is wanted. A safety buckle draws the lid down onto a sealing ring, giving leak protection that keeps meltwater inside rather than in the bottom of a bag. When the trip ends, a drain plug releases that water without tipping the cooler, and the interior rinses out easily. Anti-slip foot pads maintain stability on various surfaces, holding position on sand, decking or a vehicle floor. A user-friendly handle makes it effortless to carry one-handed, leaving it ready for beach trips, camping, travel and other outdoor activities. Assembly is required.
