The Purist WaterGate Bottle features an amorphous silicon dioxide coating that's infused into the inner-wall of the bottle. Essentially, this forms a glass-like finish that provides a totally natural, and completely inert, solution to the problem of your drinks staining the bottle or leaving behind any residual aftertaste. This infusion also shields your fresh water from tasting like plastic on very hot days, making it akin to drinking straight from a sparkling clean glass.

• Purist infusion shields the bottle from odor, stains, and mold to keep your water pure and your bottle clean.
• Simple hands-free open and close valve: Nothing to turn.
• 100% leak-proof top locks down for transport or mixing powdered drinks.
• Self-sealing Heart Valve™ delivers a high rate of flow with a 100% leak-proof design—even when the valve is open.
• Rubber over-molded on the outside of cap for easy, sure grip.
• Made from easy-to-squeeze LDPE material.
• Clear viewing strip makes it easy to see the bottle's contents.
• BPA-Free plastic is made from 100% FDA food-grade materials, and it's printed with non-solvent base (UV Cured), CPSC-approved ink and materials.
• Available in 22oz and 26oz Purist Bottles.
