We hate when our favorite beverage loses its frosty (or piping hot) goodness before we can fully enjoy it. That’s why Yeti™ over-engineered their Yeti™ Cups with kitchen-grade 18/8 stainless steel and double-wall vacuum insulation. Yeti™ dipped Cups keep ice 2X longer than plastic tumblers and are designed for maximum ice retention – and work just as well for hot beverages. Yeti™ dipped Cups are BPA free, including the crystal clear lid, so you can gauge the level of your frosty beverage as it slides down the pipe.
