I bought an extra large for my husband (who is a bug guy and we've been having a hard time finding him a mask that actually fits), and while the quality is good and the mask is comfortable, I'm going to have to figure out a way to alter it for him as it TOO big, and I can't afford to pay for another and not be able to use this one. I still recommend, as the quality is good and the shipping was pretty quick, but perhaps think about sizing down.
