MuleSkinET™, our exceptionally sturdy exterior fabric, and MuleSkinEV™, our tough interior layer, combine to create a rugged shell that protects against the elements.
Our unique PolarLayer™ Insulation foam keeps contents in our Classic, Jaunt and Pro coolers cold for over 24 hours of frosty beverages. For the Traveler series and Urbano, our enhanced insulation takes that up to 48 hours. For the BOSS, we've created an extreme insulation profile that will keep contents cold for days
This distinct feature allows extra air to be added to the insulation layer, which increases the insulating capability and it also adds buoyancy - which means the ICEMULE will float (even when full!) . The IM AirValve also allows you to release air, which allows you to compress and roll it up for travel and storage.
