The YETI Rambler Tumbler Straw Lid features a wide, durable, drinking straw that makes the perfect lid for iced coffees, sweet tea, and ice-cold water. 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 all YETI Rambler Lids, it's shatter-resistant, dishwasher-safe, and completely free of BPA. Compatible with: Rambler 16 oz Stackable Pint, Rambler 20 oz Tumbler, Rambler 24 oz Mug, and Rambler 25 oz Straw Mug.
