Take hydration head on with our biggest straw mug ever. From water around the clock to post workout protein shakes, it's your cup holder co-pilot 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 moulded-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.
