The YETI Rambler Colster is a koozie for keeping your drink cold and your hand dry and warm. Built with stainless steel, this is much more than a koozie, as it's tough and durable to make it through all your friends shenanigans. Tailgates, backyard parties, barbecues and even chilling in the deer blind, it's ready to keep that drink nice and cold. Place your drink in the Colster™, screw on the ThermoLock™ Gasket over top, and enjoy the party. Responsibly of course. A cold drink without having to hold onto a sweaty, wet can. Count me in.
