I believe this icon included is too detailed and doesn't follow the MD guidelines.
no problem :)
We still need this icon, but will have to think of a different design. Agreed with @MrGrigri.

Something like this without the tassel thing?
Maybe use face-profile for it.
Just like the @xaviergonz one, but with md guidelines

I still don't think those are material enough.
Will this do ? Maybe the top of the helmet will have to be redrawn :
