The Rambler 20 oz Tumbler with MagSlider Lid is YETI's go-to tumbler for coffee, tea, or any drink on the move, and it is sized to fit in most cupholders. It is made from kitchen-grade 18/8 stainless steel with double-wall vacuum insulation that keeps cold drinks cold and hot drinks hot, and its No Sweat exterior means condensation stays off your hands and tabletop. The color-matched MagSlider Lid is splash resistant and uses a single sliding magnet to stay open or closed. Like all Rambler Drinkware, it is dishwasher safe, BPA free, and backed by a five-year warranty. This is the Black colorway.
