WHAT’S THE IM AIRVALVE™?

Another feature found only on the ICEMULE is the AirValve. Because of the unique design of the ICEMULE, we added the AirValve so you can release the natural layer of air captured in the PolarLayer when you roll it up for storage. It has the added benefit of enhancing the insulation when you add extra air to the cooler after it’s filled up with ice and beverages. But don’t put too much air in. If you blow it up like a balloon you’ll lose capacity. Everyone eventually finds their own perfect balance with the AirValve. Please be sure to properly close your AirValve at all times.
