This is it, the entry-level ICEMULE Pro™ backpack cooler, clocking in at 23 liters of beer haulin', ice-keeping performance. The Large Pro can easily load up with 18 cans + ice, making it ideal for a day on the boat or a tailgate before the game. No other soft cooler out there is easier to carry, easier to load up and easier to unload. Along with keeping your drinks colder than cold, ICEMULE Coolers are built with welded seams and without leaky zippers, so they’re waterproof through and through. The huge bonus to being 100% waterproof: each cooler can float right along with you.
