YETI Colster The YETI Colster is like a stainless steel bear hug (or can cooler) for your sodas or longnecks. The Load-and-Lock Gasket secures your drink in place while the Colster?s double-wall vacuum insulation keeps your beer or soda frosty longer. Plus, it has a No Sweat Design, which means you say adios to damp or frostbitten hands. The YETI Colster stands 4 7/8 in high and a diameter of 3 1/2 in. All YETI Colsters are sized to fit in standard sized cup holders. 18/8 STAINLESS STEEL Made with kitchen-grade stainless steel, so they?re puncture- and rust-resistant. DOUBLE-WALL VACUUM INSULATION Keeps cold drinks cold and hot drinks hot until the last sip. NO SWEAT DESIGN Keeps fingers dry and unfrostbitten. The Rambler family is now sporting DuraCoat Color, the durable new look available for your Tumbler, Colster, or Bottle. YETI DuraCoat Color is available in four different shades: Seafoam, Tahoe Blue, Black, and Olive Green. It's designed to go on strong, and we think it's pretty good looking to boot, making it perfect for our stainless steel drinking vessels. It won't fade, peel, or crack through extended field use, and our DuraCoat Color provides additional grip to the Rambler's exterior. So whether you have your sights set on a Seafoam 20 oz. Tumbler or a Tahoe Blue Colster, our DuraCoat Color will hold up through the life of your warranty.
