Let the proprietary PolarLayer insulation of the medium Classic 15L Cooler from IceMule, in olive, keep your beverages cold on your next backcountry excursion, picnic, or tailgate party. Unlike hard-sided coolers, transporting cold drinks in the IceMule Classic is easy, thanks to its backpack-style design. Constructed of MuleSkinEV fabric, the cooler features a TriFold DriTop design that seals the same way as a roll-top dry bag, sealing in the cold and preventing leakage. Even though the cooler is sized to hold 12 cans or 5 wine bottles plus ice, it takes up little space when not in use – the IM AirValve lets you squeeze the air out of the insulation layer, so the cooler can be flattened, rolled, and stored in its included stuff sack.
