Yeti's family of Tundra coolers will take from the tailgate party to the wilderness and more. Engineered to keep cold for days, the Tundra family is made of roto-molded polyethylene for toughness (the same material as whitewater kayaks). Tundras can handle UV light, salt spray, banging around in pickups; they're even "grizzly-proof" should you ever have a visitor to your campsite. For unmatched ice retention, the extra-thick walls are filled with foam insulation and have freezer-style gaskets. Padded Double Haul™ handles make the coolers easier to carry. Self-stopping hinges allow easy access to your food and beverages at the cookout. All Tundra models come standard with one dry goods basket. Some of the sizes make a perfect extra seat at the campsite or on the boat, or a casting platform. The 35, 45, and 50 are great all-purposes sizes. The larger sizes can accommodate your grilling provisions or the game or fish from your hunting/fishing trips.
