The YETI Rambler® Colster® will make your tailgates and outdoor events all the more enjoyable. The Rambler® Colster® combines the features of a koozie and a coaster into one. Constructed with stainless steel and double-wall vacuum insulation, your beverage stays ice cold. The Colster® fits a 12 oz. can or bottle, and stays locked in with the Load-and-Lock® Gasket. Cheers with the YETI Colster®.
