Built to house 35 ounces of your favorite cold beverages, this is one hefty hydrator. Supremely insulated and made with an elevated handle and a cup holder-compatible design, it goes best with overly large cold brews, cross-country trips, and absolutely massive mocktails. And with the fan-favorite Straw Lid, you can say goodbye to single-use plastic straws. The Rambler Drinkware and Lids are built to last, shatter-resistant, dishwasher-safe, and BPA free. The Straw Lid has a molded-in stopper so your straw stays safely in place. Additionally, this mug is compatible with our MagSlider Lid. Do not use the Rambler Tumbler Straw Lid with hot beverages.
