Halo cosplay : what for the visor ?

Hello everybody !
I want to do a Halo cosplay. I think I will use styrofoam or evafoam (tell me if you used something else) but I don’t know what to use for the visor.
I searched on the 405th company site but I don’t really understand. :confused:
What should I use ? Thanks

You should ask her. I don’t know much about it but she does.
