The supremely insulated YETI Rambler Stackable Cup is built for big swigs from dawn 'til dusk. It's sized perfectly for Texas-sized teas, large gulps of H20, XL smoothies, fewer refills and retaining every degree of your drink's temp, especially when you're far too busy kickin' back around the fire. Plus, it's topped with YETI's fan-favourite Straw Lid so you can say goodbye to single-use plastic straws.  The Straw Lid is not compatible with hot beverages.
