This includes the HERC Heavy helmet. Bit sad I can't wear a mask with it like the other helmets, considering the combat helms do the exact thing.
Not sure if there are other helmets that can't be worn with masks or not.
EDIT: this only goes for helmets that have 5-10% suppression res or some injury chance, cause i can understand how some helmets could be op
