The YETI Tundra 35 Cooler is the ultra-portable model of our Tundra line, small enough to easily carry while still packing in the recommended 20 cans. Itâ€™s the best road trip companion youâ€™ll ever meet â€” some people even refer to it as their YETI Car Seat. Thanks to 2 to 3 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, or basking in the sun on your boat. And even though itâ€™s the smallest of our Tundra coolers, the 35 is still built to be grizzly proof. The Tundra 35 portable cooler also fits nicely in an inner tube, making it our best ice chest for floating down the river on a warm summerâ€™s day with a few cold beers, if thatâ€™s the kind of thing that youâ€™re into. And we very much are. The non-slip feet keep it from sliding around on your stand-up paddleboard, if you want to go a little more extreme. Wherever you decide to take it, this portable coolerâ€™s sturdy, one-piece construction will stand up to the rigors of the journey.
