Any tumbler that's coming along for the ride needs to be tough enough to keep up. The Yeti Rambler 20oz Tumbler (591mL) is made from durable 18/8 stainless steel with double-wall vacuum insulation to protect your hot or cold beverage at all costs. Like the entire Rambler family, the 591ml Tumbler and its 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:The Yeti Rambler 20oz Tumbler comes with their MagSlider lid, which is not 100% leakproof and will not prevent spills if turned sideways or upside down.
