Thermos delivers when it matters. Thermos brand products offer superior cold retention that keeps beverages cool and delicious for hours, and the 18 Oz. Stainless Steel Hydration Bottle is no exception. Thermos vacuum-insulation technology virtually eliminates temperature change within the beverage container by creating an airless space between 2 stainless steel walls. The result is a superior insulated container you can depend on to keep your beverages colder, fresher, longer. Constructed with double wall stainless steel, this Slate Blue 18 oz. bottle is virtually unbreakable and built to withstand the demands of everyday use. A comfortable silicone grip makes the bottle easy to grasp and the bottle is sized to fit most automobile cup holders. It comes equipped with a hygienic, push-button, locking lid which can be operated easily with one hand. And because of the double wall insulation, the stainless-steel body stays condensation-free with cold beverages.
