AUTOSEAL Technology – Automatically seals between sips! The 100-percent leak-proof and spill-proof AUTOSEAL lid automatically seals between sips, making it impossible to spill. There is no lid to remove or spout to open, so it is great for one-handed, on-the-go drinking whether commuting, hiking, or just dealing with a busy day. Simply press the button to drink and then release to seal between sips. And because the lid system is always closed unless activated, your beverages will remain hotter or colder for longer periods of time. Vacuum-insulation for maximum temperature retention Made from durable stainless steel, the mug’s vacuum-insulated double-wall body ensures that hot beverages stay hot and cool beverages stay cool. The 16-ounce size keeps beverages hot for up to 4 hours and cold for up to 12 hours, while the 20-ounce size keeps beverages hot for up to 6 hours and cold for up to 18 hours. This double-wall construction not only retains temperature, but also prevents external condensation from forming so table tops remain free from moisture. Dishwasher-safe lid hinges open for easy cleaning This Contigo travel mug also features an easy-to-clean lid. The lid is top-rack dishwasher safe, and its interior ice gaurd hinges open for increased visibility and water flow while cleaning. Caring for Your Contigo For easy care, the Contigo lid is top-rack dishwasher safe. It is recommended to hand wash the mug body to protect the finish. Always rinse the mug immediately after each use, and always store the mug with its lid removed to prevent moisture from becoming trapped in the body or lid after washing. Do not keep liquids that spoil easily, such as dairy, in the mug for prolonged periods.
