The Adventure 1.4 quart vacuum bottle from Stanley delivers the thermal performance you expect, in sleek, elegant stainless steel. It's lightweight, so you can add it to your pack without also adding a lot of weight. It keeps hot drinks hot for an amazing 24 hours, and if you're carrying a cold liquid, you'll get 120 hours before you notice any change in temperature. Since it's stainless steel, you know that it's BPA-free and will never rust. And like all Stanley vacuum bottles, it will never leak. Cleans up easily, too, with hand washing, or just put it in the dishwasher.
