The YETI Tundra cooler is designed for true lovers of the outdoors: guys and gals who are in the field or on a boat season after season, for whom ordinary coolers just won't cut it. Durable? Oh yes. This marine cooler is made from the same roto-molded polyethylene as whitewater kayaks. And the molded-in, self-stopping hinges mean you'll never have to replace a busted hinge again. Effective? You bet. Two to three inches of insulation, extra-thick walls and a freezer-style gasket mean you'll spend more time doing what you love and less time restocking ice. If you happen to take these top-quality coolers into bear country, don't fret - it's been certified grizzly proof.Specifications and Features: Product Model: Tundra 65
