This have probably been discussed before but I’ve tried searching the forum and come up with zero. So bare with me and point me in the right direction if it has ?   The question is as above. Would a Stunt helmet be approvable for EI and Centurion if the addressed differences below is done with it? I know they look a bit different and what I’ve read about it was that the molds where worn and also the Hero helmets done in abs plastic that made the shape of it a bit different.
