Bought 2 of these a lg. for me the same as my open face. I found it tight but I'm not used to a full face, For my wife I got a small but she found it too tight (she suffers with headachs) so we sent it back for a med. RevZilla had the replacement shipped the same day they recieved the one I sent back, no questions ask. The finish is very nice. Wish I could report on the air flow but I don't have any seat time yet.
