The Rambler™ series’ famous cold-retaining properties keep frozen beverages icy for hours, and now the Straw Lid makes them easy to enjoy. Their wide, durable drinking straw makes this the perfect lid for smoothies, slushies, and more. Unlike other insulated cups with straws, the Rambler™ Straw Lid is built to last and has a molded-in stopper that holds your straw safely in place. And just like our other Rambler™ lids, it’s shatter resistant, dishwasher safe, and completely free of BPA.
