The Purist Insulated Watergate Bottle features an amorphous silicon dioxide coating that's infused into the inner-wall of the bottle. Essentially, this forms a glass-like finish that provides a totally natural, and completely inert, solution to the problem of your drinks staining the bottle or leaving behind any residual aftertaste. This infusion also shields your fresh water from tasting like plastic on very hot days, making it akin to drinking straight from a sparkling clean glass.
The silicon dioxide coating is a mere 20 nanometers thick which, for comparison, is less than 5,000 times thinner than a human hair. Meanwhile, the shape of the bottle feels equally perfect both in the hand and in the cage.
It's fully insulated to get keep your beverages either piping hot or icy cold, and it comes equipped with our WaterGate Cap, with a self-sealing Heart Valve that delivers a high rate of flow with a leak-proof design, even when the valve is open, providing a simple drinking experience.
