The Yeti Rambler 20 oz (591 ml) Tumbler is your go-to solution for coffee on the go, designed to fit in most cupholders for easy transport. Built tough, this fan-favourite tumbler is crafted from durable stainless steel and features double-wall vacuum insulation to keep your beverages at the perfect temperature. Like all Rambler Drinkware, the 20 oz Tumbler and its MagSlider Lid are dishwasher-safe for convenient cleaning. The MagSlider Lid provides an extra layer of protection, helping to contain your drink and maintain its temperature, but it’s important to note that the lid is not leakproof and won’t prevent spills.
