Built to house 35 oz 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 better with overly large cold brews, cross country trips and absolutely massive mocktails. And with our fan-favorite straw lid, you can say goodbye to single-use plastic straws. Our Rambler® drinkware and lids are built to last, shatter-resistant, dishwasher safe and BPA-free. The straw lid has a moulded-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.
