The Excel Sports Logo 22oz Purist is made by Specialized and features the pure taste of a drinking glass in a flexible sports bottle. The Purist uses a silicon dioxide coating to create low surface tension like a Lotus leaf. This shields the inside of your bottle from odor, staining, and mold build-up. With a simple rinse of the bottle, Purist ensures that water from the bottle does not taste like plastic or the previous liquid.
An extremely thin Silicon dioxide coating is applied to the polymer structure of the inner surface of the bottle, forming the protective glass-like barrier that prevents odors, stains, and mold from permanently attaching to the inside surface of the bottle. Silicon dioxide is an inert compound made from two of the most abundant elements in the earth's crust: silicon (not to be confused with the chemical silicone) and oxygen. An Excel Sports staff favorite.
Cleaning instructions: do not scrub or scratch the interior of the bottle, just rinse or wash on the top rack of the dishwasher
