The only bit of fluff I could find regarding Scout Helmets is in a Black Library short story about a Wolf Scout who is piloting his own space ship on some sort of mission. I completely forget the name of the story, but at some point the Scout makes a comment about how he doesn't like wearing the helmet because the face plate is all glass and they tend to shatter and cut up your face.
Given this, I wanted glass faced helmets.

I'd definitely recommend you check out the website and give them a shot.
