We over-engineered these double-wall insulated tumblers with an 18/8 stainless steel body, which means your drink still keeps its temperature no matter how much of a beating this cup takes. These Yeti Ramblers come standard with our Yeti MagSlider lid, the only drink lid that uses the power of magnets to keep your water, beer, or favorite drink on lock. Any tumbler that's coming along for the ride needs to be tough enough to keep up. Our fan-favorite Rambler 20 oz. 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 20 oz. 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.
