The YETI Rambler Colster 12oz Can Cooler is an insulated can cooler for cold beverages at camp, on the boat, and at the beach. Pull a 12-ounce can out of the cooler and slip it into the double-wall insulated colster, securing it with the quick-turn gasket. It keeps the drink cold in the hot summer heat and features a No Sweat design, so hands stay dry from condensation. Cheers, friends.
