Ultimate portability. Ultimate ice retention. Ultimate ease of use. No wonder the ICEMULE BOSS is the ultimate cooler. You can finally have frosty cold beverages, hour after hour, day after day, mile after mile. Premium, multi-day ice retention paired with a best-in-class suspension system lets you go the distance and rest assured knowing you've got the best backpack cooler ever made.
Engineered like a premium technical backpack, this cooler goes places where no other cooler would even think about going. It keeps drinks colder, longer. It moves the way you move. It just plain gets the job done-especially when that job is keeping ice, ice-cold. Starting today, your cooler is officially one less thing to worry about.
This cooler will keep ice for days. Period. The BOSS is surrounded by a 3cm closed-cell PolarLayer XT Insulation foam giving you true multi-day ice retention. You can add air with ICEMULE's exclusive IM AirValve to achieve a level of insulation that is literally unmatched by any cooler.
The BOSS has a best-in-class backpack suspension system that includes ventilated airmesh back pads & carrying straps, cushioned hip belt, and a sternum strap that wraps you in supreme comfort. Carrying a cooler has never been this comfy.
The BOSS is equipped with our wide-mouth, Tri-Fold DriTop enclosure, providing hassle-free access to your coldest contents. You can load this extreme cooler by yourself, and without losing skin to a zipper.
Three oversized pockets make the BOSS the most versatile cooler ever created. Every pocket on the BOSS is outfitted with super-tough PakShield zippers that keep water out and everything inside dry. Plus, they're padded and insulated, meaning they can keep things secure and cold (if needed).
With welded seams, and proprietary MuleSkin fabric, the BOSS is completely waterproof and will last for years. Plus, it can easily handle over 60lbs of weight. The only question is, can you?
Somewhere along the line you were led to believe a cooler must be a box. Something you sit on. Something you have to lift with all of your might. Something you put down and leave behind. But that's no way to live. Sitting down-On a box, Constrained to one spot.
So we set out, not to start a company, but to start a quest. To change the cooler as you know it. To make it softer, yet stronger. To take it further, literally. To break boundaries and beliefs on where coolers should be able to go. And to push our own expectations of just how cold cold can be. To strap the world on our backs with comfort and convenience. To leave convention behind, and to curiously, courageously and confidently CARRY ON.
How We Got Started
The ICEMULE resulted from a simple need: to carry a real cooler - one that carries real ice - comfortably and easily.
The idea was born on a hot, spring day when founder James Collie was taking a day-long hike with friends in Virginia. Knowing they wouldn't be able to stop for cold drinks along the banks of James River, and unable to find a good waterproof portable cooler, James created a make-shift cooler out of a day pack and double lined it with plastic trash bags. Inside, he filled it with cold drinks and sandwiches.
This seemed like a good idea until the trash bags broke and ice water flooded down his back. A wet hiker, warm drinks and soggy food started the wheels of innovation turning. Once home, he set out to design a soft-sided, waterproof and portable cooler that could carry ice and be comfortable enough to take on both long hikes and relaxing days at the beach.
Several months, dozens of prototypes and many days of field testing later, the ultimate soft-sided backpack cooler was born.
