An ideal choice for people on the go, the Thermos brand 16 ounce Stainless Steel Drink Bottle 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 two stainless steel walls. The result is an insulation layer that performs better than any other. A superior insulated container you can depend on to keep your beverages, colder, hotter, fresher, longer. This drink bottle keeps beverages hot for 12 hours and cold for 24 hours, making it a great choice for long days out and about or in the office. Constructed with double wall stainless steel, this 16 ounce drink bottle is virtually durable, yet its sleek design is both eye-catching and functional. It features a locking lid with one-handed push button operation that is made with BPA-free Eastman Tritan polyester to resist stains and provide durability. The bottle and lid are dishwasher safe for easy care and use.
