Meet the cooler that started it all and gave us the freedom to go further with drinks in tow. Let the exploration begin, leaving your hands free to enjoy colder beverages than ever before. The IceMule keeps your drinks ice-cold for up to 24 hours. It’s completely waterproof with welded seams and no zippers, which means it even floats. Or, roll it up for easy storage while you contemplate the next excursion.
