The Thermos Stainless King Vacuum-Insulated Travel Mug is the ideal choice for people on the go. It is built to last and loaded with features to make for a more enjoyable drinking experience. Thermos vacuum-insulation technology virtually eliminates temperature change within the beverage container by creating an airless space between the two stainless steel walls. The superior insulated container performs better than others. This travel mug keeps beverages hot for five hours or cold for nine, making it a great choice for long days out and about or in the office. Constructed with double wall stainless steel, this 16 ounce travel mug is virtually durable, yet its sleek design is both eye-catching and functional. The contoured body shape is easy to grip and fits most automobile cup holders and is single serve compatible. For tea drinkers, a built-in tea hook is just the ticket to brew tea on the go. The tea hook can also accommodate most loose leaf infusers.
