The Mayfly 14L Cooler keeps contents cold and packs away easily. Designed as The Original Puffy Cooler, it molds to any bag, compresses into a built-in stuff sack, and is remarkably lightweight at under 15 ounces. Its leakproof, seam-welded liner ensures no messes, while the exterior zippered pocket holds essentials. Independent tests show it can keep 7lbs of ice frozen for 55 hours. Backpack straps add carrying versatility, making it ideal for picnics or carrying up to 15 cans.
