The Rambler® series’ famous cold-retaining properties keep frozen beverages icy for hours, and now the Straw Lid makes them easier to enjoy. The wide, durable drinking straw makes this the perfect lid for 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 molded-in stopper that holds your straw safely in place. And just like other Rambler Lids, it’s shatter-resistant, dishwasher-safe, and completely free of BPA. YRAM20STRAW fits 16 oz. Pints, 20 oz. Tumblers and 25 oz. Straw Mugs. YRAM30STRAW fits 26 oz. Cups, 30 oz. Tumblers and 35 oz. Straw Mugs.
