Take hydration head-on with the biggest straw mug ever. From water around the clock to post-workout protein shakes, it's your cupholder co-pilot for sips that don't stop on days that don't either. And with the fan-favourite straw lid, you can kiss single-use straws goodbye. Like all Rambler® drinkware, the mug and lid are dishwashersafe. The Rambler® straw lids are built to last and have a moulded-in stopper that holds your straw safely in place. And just like the other Rambler® straw lids, it's shatter-resistant, dishwasher-safe, and completely free of BPA. Additionally, this mug is compatible with the MagSlider™ lid.
