Brumate's 12oz Rocks tumbler is designed to give your favorite drink a superb presentation while allowing you to pour a generous amount. Designed with a classic square bottom and round rim, impressive sleek lines accent the base while Brumate's BevGuard™ technology guarantees your drinks stay ice-cold and refreshing or nice and warm, without the metallic aftertaste other stainless steel products often have. So sip back and relax, because drinks are better with BrüMate. Splash-proof lid included.
