ICEMULE strives to make products that make life more portable. In 2014 we launched our Kickstarter campaign to bring the original ICEMULE coolers to life. They were designed with the IM airvalve. This technology makes ICEMULE very unique. The IM airvalve allows you to add air to the insulation layer for extra ice retention and buoyancy while on the water. It also allows the coolers to be rolled up so that you can go wherever you want, whenever you want.
