>>63981077 (OP)Both skull cap and CVC helmet have their own advantage and drawback
For example, russian style skull cap has looser tolerence so it can be easily mass produced, easily replaced and can be issued to any person with normal sized head. Also the few guys that I've spoken too said it's much more comfortable to wear and can double as a makeshift pillow
The drawback is that you hav to wear comm separately. That piece of fabric where earpiece supposed to hang to? Yeah that's going to rip off in no time
