A 3-layer insulation build keeps this 37-quart chest cold, warm or simply fresh for up to 3 days, which covers most weekend trips without a second bag of ice. The 17.5 by 11 by 11 inch interior takes drinks, produce and packed meals, and both the inner and outer shell are rated to 110 lbs, so the closed lid works as a seat when the folding chairs run out. Molded side handles make the 14-pound box easy for one person to carry from the trunk to the sand. Practical extras sit where you need them: 2 cup holders on the lid, a fish measuring ruler along the body, a bottle opener at the front and a leak-proof drain plug at the back. The PP and ABS shell measures 23 by 14 by 14 inches overall and wipes clean in a minute.
