Product Description

Double-walled and vacuum-sealed stainless steel (304 stainless 18/8) - keeps contents hot or cold for hours Perfect of hot or cold beverages - does not sweat (for cold contents) or burn your hand (for hot contents) Contoured design - makes the bottle easy to hold and visually distinctive from the many, many straight-walled bottles Removable mesh filter - keeps ice from blocking the drinking spout and allows users to conveniently brew tea on the go Unsurpassed testing for material safety - our products undergo rigorous chemical and biologic testing to insure they do not contain toxic chemicals. No internal liner. All Thinksport bottles are super insulated to keep the contents cold or hot for hours. You can fill our bottle with ice and your favorite drink and enjoy a cold drink without the bottle sweating all over your gym bag, backpack, or desk. All of our bottles also feature a wide mouth opening (for ease of filling and cleaning) and a smaller polypropylene spout (for convenient drinking). We've also built in unique functionality like an interior mesh filter that keeps ice from blocking the drinking spout and allows users to brew tea on the go. So, you get a high-quality insulated sport bottle for about the same price as the other guys' basic single-walled bottles.
