TCRC 22oz Insulated Stainless Steel Water Bottle with Leak-Proof Lid - BPA Free, Keeps Drinks Cold/Hot for 24 Hours - Perfect for Gym, Hiking, Travel & Office (Black)

The Purist MoFlo 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.
