The YETI Tundra 420 is the largest YETI Cooler. The preferred cooler of big-game hunters, wilderness guides, professional marine fishermen and fishing charters, this behemoth has plenty of room to stash the largest yellowfin and wahoo, and can even hold an elk or a moose. The extra-thick walls and 2-3 inches of polyurethane foam insulation keep whatever youre bagging colder, longer and is dry-ice compatible. The rugged, roto-molded construction ensures it will last trip after trip. And its not only at home in the outdoors, the extra-large capacity and legendary YETI ice retention make it a perfect cooler for restaurants, bars and catering operations.
