Rambler Tumblers are the carry-size, sip-on-the-go cousins of the screw-cap, leakproof Rambler Bottles. They fit in virtually all car and truck cupholders. Hate it when your favorite beverage loses its frosty (or piping hot) goodness before you can fully enjoy it? That’s why the Rambler Tumblers have been over-engineered with kitchen-grade 18-8 stainless steel and double-wall vacuum insulation. Rambler Tumblers keep ice 2 times longer than plastic insulated tumblers and are designed for maximum ice retention. And they work just as well for hot beverages. Rambler Tumblers are BPA free, including the crystal clear lid, which lets you gauge the level of your frosty beverage as it slides down the pipe. Tumblers now come with Yeti's popular and ingenious Magslider closable lid, so you can leave the sipping hole open for use, or closed to prevent spills and splashes when the going gets rough - whether in a vehicle or on foot. These bare stainless steel Tumblers are also available in colorful DuraCoat versions. See Related Products, below.
