The Specialized Purist Fixy 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.

Features:

• Purist infusion shields the bottle from odor, stains, and mold to keep your water pure and your bottle clean
• Large screw top design is leak-free and wide enough for ice cubes and scooping in powdered drink mix
• 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
