The Rambler® 30 oz. is the tumbler that gets you through the day. Your morning brew stays hot, and your iced coffee will stay cold - so take your time. Kitchen-grade stainless steel with double-wall vacuum insulation will protect your drink at all costs. Like the entire Rambler Family, the 30 oz. Tumbler and whichever lid you put on it are dishwasher-safe for easy cleaning.
