The Purist MoFlo bottle features 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 any aftertaste.

This infusion also prevents fresh water from tasting like plastic on very hot days, making it like drinking straight from a sparkling clean glass.
