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. While the magnet on the included MagSlider™ Lid adds an additional barrier of protection for keeping drinks contained and preventing heat or cold from escaping, please note - this magnet component is not leakproof and will not prevent spills. Our durable 18/8 stainless steel tumblers are built to resist dents and dings. No Sweat™ Design keeps hands dry, and protected from hot and cold drinks. Plus, the Rambler 30 oz comes with a MagSlider™ Lid and both are dishwasher safe.
