The Rambler series' famous cold-retaining properties keep frozen beverages icy for hours, and now the Straw Lid makes them easier to enjoy. Our wide, durable drinking straw makes this the perfect lid for margaritas, slushies, and whatever drinks you'd rather sip than gulp. Unlike other insulated cups with straws, the 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 Lids, it's shatter-resistant and completely free of BPA.
