Just think of the convenience in your busy life if your drink bottle could close itself automatically. Using Austoseal technology, this sleek Jade green travel mug allows you to toggle the button to drink and as soon as it is released, the outlet will automatically seal itself! Spill-proof and leak-proof and with a 473ml capacity, this Contigo Westloop Autoseal Travel Mug is the perfect choice in the car, at the office or gym and whenever you want to enjoy a refreshing hot or cold drink. Made with double-walled stainless steel and vacuum sealed, this attractively contoured mug keeps hot drinks piping hot for up to 7 hours or cold drinks cold for 12 hours. The wide mouth allows for the addition of ice cubes and the twin walls mean there can never be any messy condensation on the outside. Save money and make the ethical choice when you choose to make disposable plastic water bottles a thing of the past and make the change sustainable living.
