IceMule Classic Cooler Bag

The ICEMULE Classic^™  Cooler bags are the ideal cooler in three sizes. Keeps drinks frosty cold for up to 24 hours.  The sturdy exterior fabric helps create a shell for your cooler bag.  Zipper-free with roll top closure.  An air valve allows extra air to be added to the insulation layer, which increases the bag's insulating capability and it also adds buoyancy - which means the ICEMULE will float (even when full!) . This valve also allows you to release air, which means you can compress and roll it up for travel and storage.
