With the YETI Rambler 20oz Tumbler, your beverages will stay ice cold or piping hot longer. YETI over-engineered these double-wall vacuum 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. This handsome cup has a No Sweat Design to make sure your hand (and table) stays dry, and it's dishwasher-safe. It comes standard with the handy YETI MagSlider Lid, which harnesses the power of magnets to keep your sodas or suds on lock.
