Specialized Purist Water Bottle Clear 26oz
As pure as drinking from a glass with all the advantages of a flexible bottle. The Purist bottle is infused with silicon dioxide, which is then added to the polymer structure of the inner surface of the bottle, forming a protective glass-like barrier that prevents odors, stains, and mold from permanently attaching to the inside surface of the bottle. The barrier is an extremely thin 20 nanometers; over 5,000 times thinner than a human hair.
