IceMule Boss Cooler

In addition to impressive multi-day ice retention, the Boss is engineered like a premium technical backpack, complete with a best-in-class suspension! The cooler features 3 cm closed-cell PolarLayer XT™ Insulation foam, and an IM AirValve™ lets you add extra air to achieve an even higher level of insulation. A wide-mouth Tri-Fold DriTop™ enclosure allows for easy loading and access to contents. Made of proprietary MuleSkin™ fabric, the Boss also features welded seams, is completely waterproof, and can handle over 60 lbs. of weight. The three oversized, padded, insulated pockets feature super-tough PakShield™ zippers that keep out water. Ventilated airmesh back pads, shoulder straps, a cushioned hip belt, and a sternum strap offer supreme comfort.
