Ive seen them before without the lights of course. I cant think of their name off the top of my head, but give me a few minutes and I will pull you a link. I do know the U.S. homeland security government uses them and their cost is considerably high as gas masks go.





I think this is the drummers with a tdifferent filter http://www.centerfiresystems.com/gasmask鈥?/a>





They are using different ones of course.





Actually I am not sure what he has, it wasent the one I was thinking of.
Hey, hell if I know, but I do know, I saw this dude who is really into collecting gas masks, he is on You Tube. Just do a search for gas masks, then send it to people who are really into it, if you can find that guy, he would be able to tell you...
