This 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. The 30 oz. Tumbler and whichever lid you put on it are dishwasher-safe for easy cleaning. The lid adds an additional barrier of protection for keeping drinks contained and preventing heat or cold from escaping.
