The all-new Icemule Boss Cooler is an extreme cooler that’s designed to ensure cold for a long time and guarantee maximum portability. Most of the coolers on the market are either bulky and hard to carry around, or can´t keep things cool for too long. The Boss aims to get the best of both worlds, the cold will stay for days because of its proprietary design, it uses a 3cm closed cell of PolarLayer XT Insulation that can be enforced through the use of the IM Air Valve, this will upgrade insulation should you need some more, simply fill it with air and you get that extra layer. Portability is ensured by its effort in keeping it lightweight, it features padded shoulder and hip straps and a suspension system aimed at ensuring your comfort. It’s also super tough, with welded seems and exclusive MuleSkin Fabric that makes it completely waterproof and will last for years of heavy duty use. Plus it will also float should it fall in water and has loads of Molle webbing and clipping points for extra loads.
