Make it, shake it, and take it on the go with the leak-proof Streeterville Shake & Go Tumbler, 20 oz. The removable, easy-sipping straw might look elegant from the outside, but the Streeterville Shake & Go Tumbler loves to get a little crazy and shake things up. Iced tea, coffee, and water enhancers, to more (ahem) adult beverages can be mixed with no leaks thanks to the AUTOCLOSE lid. This cold beverage tumbler fits most car cupholders, making it both commuter- and dropoff-the-kids-at-school friendly. Double-wall construction comes in clutch on the daily, keeping sweat to a minimum so you can wet your whistle without getting your laptop or gym bag wet, too. When it's time for a quick cleaning, let the dishwasher do the work for you--straw, lid, and body are top-rack safe.
