This is the stainless steel water bottle that will not leak—even when inverted and shaken vigorously. The lid creates a perfect seal with the water bottle and locks into place with the integrated button and clasp, preventing any water from escaping. Pressing the button instantly opens the lid, providing easy, one-handed access to the contents. The dual-walled vacuum design keeps water cold without transferring the temperature of the liquid to the exterior or causing condensation. Its handleless, slim design enables easy storage in a car's cup holder or a backpack and the stainless steel construction resists damage and helps maintain the pure, refreshing taste of water. Hand wash. 18-oz. capacity. 10" H x 2 1/2" Diam.
