YETI's 12oz. Colster features the sleek design and stronger gasket which we have all come to know and love. This size is perfect for sparkling water, soft drinks, and good old-fashioned beer - all kept 'straight-from-the-cooler' cold. Enjoy the double-wall vacuum insulation technology which will keep your hands dry while kicking back on the boat, relaxing at camp, or soaking in the rays at the beach. Either way, you are ready to party!
