A water bottle is not just a water bottle. We've all had the ones that are hard to fill, likely to leak, or difficult to clean. So, when you get one you love it gets used a lot. We love the Purist bottles because they check all the boxes and last virtually forever. We recommend a matching set. Features: Purist technology shields the inside of the bottle from any bad taste, mold, or staining. As pure as drinking from a glass, but with all the advantages of a flexible bottle. Nothing sticks, so your bottle stays clean 22 oz MoFlo cap
