With the Rambler 18 oz. Bottle, your beverages will stay ice cold or piping hot longer. Yeti over-engineered these double-wall insulated tumblers with an 18/8 stainless steel body, which means your drink will hold its temperature no matter how much of a beating this cup takes. Our Ramblers are BPA-free (obviously), have a No Sweat™ Design to make sure your hands stay dry, and are dishwasher-safe. All to say, these Rambler Tumblers are the YETI cups that will keep your drink cold (or hot) until the very last sip. Custom printed with Franklin Barbecue logo.
