The YETI RamblerA(R) series' famous cold-retaining properties keep frozen beverages icy for hours, and now the YETI RamblerA(R) Straw Lid makes them easier to enjoy. The wide, durable drinking straw makes this the perfect lid for iced coffee, sweet tea, margaritas, and whatever drinks you'd rather sip than gulp. Unlike other insulated cups with straws, the RamblerA(R) Straw Lids are built to last and have a molded-in stopper that holds your straw safely in place. And just like all YETI RamblerA(R) Lids, it's shatter-resistant, dishwasher-safe, and completely free of BPA.Compatible with: RamblerA(R) 16 oz. Stackable Cup, RamblerA(R) 20 oz. Stackable Cup, RamblerA(R) 20 oz. Tumbler, RamblerA(R) 24 oz. Mug, and RamblerA(R) 25 oz. Straw Mug.
