Tundra Coolers Meet the original YETI the Tundra. This was our baby. Where it all started. Where we took our frustrations with cheap coolers and over-engineered the hell out of them. We ended up creating a whole new category of coolers with legendary toughness and famed ice retention. And now we make the rugged, all-purpose Tundra in enough sizes to fit any outdoor adventure. There's a good bit of its DNA in all the other gear we make too, in the form of patented and envied innovations. We're proud to see the Tundra has grown up to be the father of all coolers.
