The YETI Tundra® 45 combines versatility with durability. This premium cooler is infused with that legendary YETI toughness, a durable rotomolded construction and up to two inches of PermaFrost™ Insulation. Which is to say it's built to last and will keep your contents ice cold even in sweltering conditions. When the YETI founders started the brand in 2006, they had one mission – to build a cooler that could be used every day. The label’s collection includes well-thought-out products for outdoor enthusiasts.
