Any tumbler that's coming along for the ride needs to be tough enough to keep up. Our fan-favourite Rambler®591 ml Tumbler is made from durable stainless steel with double-wall vacuum insulation to protect the temp of your beverage at all costs. Like the entire Rambler® Drinkware Family, the 591 ml Tumbler and MagSlider™ Lid are dishwasher-safe for easy cleaning. 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. 

Warning: Do not place mug over external heat source or open flame. Vacuum seal or other damage may occur.
