These Superior Coffee engraved 20oz. Tumblers by RTIC are super sturdy, stainless steel, and double wall vacuum insulated. They will keep your drinks ice cold longer - and hot beverages piping hot!  The included all-new shaded Splash Proof lid lets you know exactly how much drink you have left. The flip-top closure resists spills and is straw friendly.  This particular design is also very easy to hand clean.
Quality that is OVERBUILT. NOT OVERPRICED.
