Made from durable, double-walled, vacuum-insulated 18/8 stainless steel that keeps liquids cold for up to 20 hours or hot for up to 58 hours. The one-button AUTOSEAL seals the bottle between sips to eliminate spills and leaks, and a patented slide lock prevents accidental button presses while you're on the go. A protective spout cover is included to keep dirt and germs out of your mouthpiece, and the "DropDown" lid feature makes it easy to clean. When you're really parched, you'll appreciate the high-flow spout that lets you hydrate quickly. With this 40-ounce BPA-free bottle by your side, no heat wave or polar vortex stands a chance.
