Timeless style meets advanced functionality with the Streeterville 40 oz Tumbler. This timeless classic gets a trend-forward makeover and updates such as a multi-use lid that allows you to sip with a straw or directly from the mouth. No matter which you choose, the Streeterville 40 oz is fully leak-proof so you can stay hydrated without the mess while on the move. With double-wall stainless steel vacuum insulation, it keeps drinks cold for up to 29 hours, helping you keep cool when the heat just won't quit. It's also built for your on-the-go lifestyle thanks to an easy-carry handle and compatibility with most cupholders. Made with all BPA-free parts, the lid is top-rack dishwasher safe while the body is fully accessible for washing by hand.
