The Purist Hydroflo MoFlo Water Bottle by Specialized features a special coating made of amorphous silicon dioxide that is infused into the inner-wall of the bottle. This coating creates a glass-like finish, ensuring that your drinks don't stain the bottle or leave any aftertaste. It also prevents your water from tasting like plastic, even on hot days.The coating is extremely thin, measuring only 20 nanometers. This makes it 5,000 times thinner than a human hair. The bottle itself has a perfect shape that feels comfortable in your hand and fits securely in your bottle cage.This version of the bottle comes with the Hydroflo MoFlo cap and bottle shape. The cap has a large screw top that can accommodate ice and powder mixes. The Hydroflo design also features a new three-shape structure, improving both the handling of the bottle and its position within your cage.To clean the bottle, we recommend a simple rinse and dry after use. If you prefer to wash it, be careful not to scratch the inner surface. Alternatively, you can safely place it on the top rack of your dishwasher.Note: This version of the bottle does not include a part number or color descriptor in the title.
