The Yeti Rambler Colster 2.0 is an insulator for your 12 ounce beverage. At camp, boatin' the waters, chilling in the backyard and so much more. Where your cooler and drinks are, the Rambler Colster 2.0 isn't far behind. The upgrade lies in the Load-and-Lock Gasket, which needs just a quarter-turn to lock in your canned beverage. Pop, beer, soda or whatever, if it's in a 12oz can, this will keep it colder for longer out in the hot sun.
