A Purist water bottle is pure bliss. Fresh tasting water in an insulated 23 oz reservoir that keeps it cold, and doesn't taste like plastic! 

Do you like drinking from plastic? Do you prefer glass but don't want the weight? How about something that tastes like glass but is plastic? Purist bottles are as pure tasting as drinking from a glass – with all the advantages of a flexible water bottle. These water bottles are perfect for running water bottles and go great with our Hydraquiver packs.

The all-new Purist Insulated features a Chromatek™ liner—a proprietary insulating barrier that lines the core to keep your liquids cold. Not only do your liquids stay cold, but new squeezable materials allow for unmatched flexibility.

The Purist Insulated Chromatek™ bottles use an amorphous silicon dioxide coating that has been infused into the inner-wall of the water bottle. This forms a glass-like finish that provides a natural, and 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 similar to drinking straight from a sparkling clean glass.
