Neutral flavour, what does it mean?
This water bottle emerged out of an innovative process involving an odourless and neutral-tasting plastic material.Rinse your water bottle with clean water 3 times before using it.Then, dry it upside down without the mouthpiece. Then remove the bite valve to clean it.This is particularly important if you are using sugary drinks!
Finally, so that it doesn't make noise while you are running, remember to remove any air by sucking out the air bubbles.
