The YETI Tundra® 35 is the right size for personal hauls or food for a small crew. It boasts up to three inches of PermaFrost™ Insulation and a rugged rotomolded construction for optimum adventure performance. And it fits nicely in an inner tube, making it the perfect, portable cooler to take tubing down the river. YETI makes gear that’s built for the wild. The brand was conceived to build the cooler that could stand up to your adventures, and still bring cold drinks to the cleaning table or campfire afterwards.
