The Yeti Coolers Tundra 35 is small enough to easily carry while still packing in up to 20 cans. Thanks to 2 inches of cold-retaining insulation and extra-thick walls made from UV-resistant polyethylene, this cooler will keep your ice icy whether riding shotgun with you in the A/C, securely strapped to the back of your ATV. The Tundra 35 is built to be grizzly proof*. The Tundra 35 portable cooler also fits nicely in an inner tube, making it the best ice chest for floating down the river on a warm summer's day with a few cold beers, if that's the kind of thing that you're into. The non-slip feet keep it from sliding around on your stand-up paddleboard. Wherever you decide to take it, this portable cooler's sturdy, one-piece construction will stand up to the rigors of the journey.
