The ICEMULE is manufactured with a focus on quality, strength and utility. That’s why the ICEMULE Cooler is tough, portable and durable. Specifically, the ICEMULE’s waterproof ‘skin’ is welded together using a method called radio-frequency welding, which actually fuses the material together at the seams. This way of creating the ICEMULE doesn’t require stitching, which means the ICEMULE is totally waterproof.
All ICEMULE Coolers have an inner shell that is 3x thicker than the average soft side cooler. Every ICEMULE is made with a heavy-duty waterproof exterior. The Pro, Pro Catch and Boss all have a 1000 denier tarpaulin fabric exterior; the toughest soft cooler shell out there that will take whatever you throw at it.
