The new Purist Insulated features our Chromatek coating, a patented insulating barrier that lines the core to keep liquids cold. Not only do liquids stay cold, but new squeezable materials also allow for unrivaled flexibility.

Purist Insulated Chromatek bottles continue to feature an amorphous silicon dioxide coating that is infused into the inner wall of the bottle. Essentially, this forms a glass-like finish that provides an all-natural, completely inert solution to the problem of your beverages staining the bottle or leaving a residual aftertaste.

This infusion also prevents your fresh water from tasting like plastic on really hot days, making it like drinking straight from a sparkling clean glass. Finally, our Watergate stopper features our Heart Valve that opens and closes without the need for use hands.
