Say hello to the cooler that fits in your carry-on bag and weighs less than a can of soup. Sick of lugging heavy coolers? So were we. This thing is light as a feather and cold as ice. We redesigned our flagship cooler from the ground up to be better in every way. Better insulation, 100% leakproof, a zipper carry-all pocket, attachments for optional backpack straps, zippered top, and the highest quality materials.
