The Excel Sports Logo 23oz Purist Insulated Bottle is made by Specialized and features the pure taste of a drinking glass in a flexible sports bottle, and a 3-layer insulation zone that keeps your liquids 22% cooler than the insualted competition. Like all Purists, the Purist Insulated uses a silicon dioxide internal wall coating to create low surface tension, like a Lotus leaf. With a simple rinse of the bottle, Purist ensures that water from the bottle does not taste like plastic or the previous liquid.

To achieve the simplicity of care and optimal health, 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. Aside from the serious material science, the mechanical aspect of the bottle, the drinking spout top, won't be outdone. The Specialized MoFlo top opens easily and closes securely, while providing an easy, steady water stream. Excel Sports staff favorite insulated bottle, hands-down.
