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.
The IM AirValve is a distinct feature which 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.
