These are the best masks I have found, and I have gone through many different kinds. It fits well but allows me to breath and speak without feeling like I'm running out of breath or that I'm going to inhale the mask at any moment. The only reason I am not giving a 5 star is because I bought the visosuppress masks and there is nothing, either in the packaging or anywhere else, that actually confirms this is what it is. It looks like all the other masks on the website and I don't really know if I received the more expensive masks that I paid for.
