I bought the helmet from a really neat guy on ebay that makes cobra helmets. I have perfect vision thru it, it is like a motorcycle visor. I think the helmet is fiberglass tho it might be resin, I dont know much about that stuff. It has a chinstrap so it cant fall off or move around but its super comfy. I had a blast running around as the Commander.
Oddly enough, the people that didnt get it at first, once I quoted the FCC episode of Family guy, knew who I was.
But one lady wanted to know what star wars character I was, and when I told her I was from GI Joe and she said well now I know, I said "And knowing is half the battle!" and it went right over her head.
