The Purist Hydroflo 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.

The silicon dioxide coating is a mere 20 nanometers thick which, for comparison, is less than 5,000 times thinner than a human hair. Meanwhile, the shape of the bottle feels equally perfect both in the hand and in the cage.

This version has our Hydroflo MoFlo cap and bottle shape. It features a large screw top to accommodate ice and powder mixes. Additionally, the Hydroflo design features a new three-shape structure that not only improves the actual handling of the bottle, but it also secures its position within your cage. 

We recommend a simple rinse and dry after use, but if you want to wash it, take care not to scratch the inner surface of the plastic. Alternatively, it'll be fine on the top rack of your dishwasher.
