If you've ever watched your coffee cool down in real time or your iced drink turn warm by lunchtime, you know the frustration. The YETI Rambler 20 oz tumbler is built to solve that problem with double-wall vacuum insulation that genuinely keeps cold drinks cold and hot drinks hot—without relying on ice or frequent reheating. That sealed chamber between the inner and outer stainless steel walls does the heavy lifting, so your morning pour stays the way you intended it through your entire day.
Thoughtful Design That Fits Your Life
The MagSlider Lid snaps magnetically into place, giving you a clean drinking edge while helping reduce heat loss as you move. The tumbler stands just under seven inches tall and fits standard car cup holders, so it slides into your morning commute, your gym bag, or your office desk without fuss. And because YETI used the "No Sweat Design"—meaning the exterior stays dry thanks to that vacuum insulation—you won't leave condensation rings on your dashboard or desk.
Materials That Actually Last
Built from BPA-free 18/8 stainless steel, this tumbler won't absorb or transfer flavors between drinks. Switch from coffee to iced tea to cold brew without any ghost tastes lingering. The Duracoat finish is engineered to resist cracking, peeling, and fading through years of daily use—the color stays vibrant whether you're using it through summer heat or winter cold. Both the tumbler body and lid are dishwasher safe, so cleanup is genuinely effortless.
