That's the ebairsoft mesh cover in MC. I painted it orange as I intended to use my FAST for SAR instead of the crappy one they provide... but for insurance reasons, I can't use anything other that what we got issued
(oh and I later removed the reflective tape with the APOS-blablabla, that was a placeholder until I got the actual tape they have on the other helmets).
That's a real Base Jump in M/L, by the way. Might fit differently with repros.
I basically cut around the rail, but you could also just remove the rails, put on the cover, then rescrew the rails over the cover. That'd be much more secure, actually.
