Dedicated tennis players will love our 20 oz. stainless steel tennis tumbler, engraved with our bold "Eat. Sleep. Tennis." design. This tumbler is designed with double-wall vacuum insulation that helps to ensure that hot beverages stay hot and cold beverages stay cold for as long as possible so they can be enjoyed at, or near, optimal temperatures for an extended period of time. A great tennis gift for any passionate player or for the whole team - and one that is perfect for commuting, traveling, or everyday use.
