Take hydration head-on with our biggest straw mug ever. From water around the clock to post-workout protein shakes, it's your cupholder copilot for sips that don't stop on days that don't either. And with our fan-favorite straw lid, you can kiss single-use straws goodbye. Like all Rambler drinkware, the mug and lid are dishwasher safe. Our Rambler straw lids are built to last and have a molded-in stopper that holds your straw safely in place. And just like our other Rambler straw lids, it's shatter-resistant, dishwasher-safe, and completely free of BPA. Please note that this lid is not for use with hot beverages.
