CAPACITY, COMFORT AND EXTREME PORTABILITY. The ICEMULE Traveler is like nothing you've ever seen before. We built it to be the most accessible, easy-to-carry soft-sided cooler around. Our exclusive Bowhead Top opens wide and stays that way, so you can get what you want, when you want, hassle-free. Our 100% waterproof PakShield top zipper keeps your back dry and our exclusive butterfly strap makes carrying the Traveler  a snap. And, as the name suggests, this cooler even doubles as incredibly durable luggage for your adventure travels.
