YETI Rambler 20
With the Rambler 20 oz. 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.
YETI Ramblers are BPA-free (obviously), have a No Sweat™ Design to make sure your hands stay dry, and are dishwasher-safe.
