I have an Airmate 3 helmet, face shield and face seal system that has served me well for over 16 years. It seems that this system has been discontinued. Airware America still has some face shields and overlays left, but no Tyvek faceseals. I have tried to find some with no luck. I like this system and have no intention of changing it. Rob Wallace replied to my add and said he makes them. How do you do that and does anyone else have a solution Thanks.
