The YETI Rambler® 26 oz Stackable Cup with Straw Lid is sized perfectly for Texas-sized drinks, fewer refills, and retaining every degree of your drink's temperature, especially when you're far too busy kickin' back around the fire. This cup is made from 18/8 stainless steel which encases a double-wall vacuum insulation that keeps drinks cold to the last drop. The Rambler® features a No Sweat™ design that is sized to be by your side through every road trip and morning commute and is covered by a DuraCoat™ color that won't peel or crack. To make things easier for you, this cup is dishwasher safe and made to stack and stow perfectly. YETI's Straw Lids are built to last and have a molded-in stopper that holds your straw safely in place, and just like the other Rambler® Lids, it is shatter-resistant, dishwasher-safe, and completely free of BPA. The YETI Rambler® 26 oz Stackable Cup with Straw Lid is built for big swigs from dawn 'til dusk.
