What are advantages of articulated cheek flaps?
Cheek guards help protecting the wearers face and side of head. Which is why many helmets had some. My question is what is the advantage of articulated cheek flaps over cheek guards that are part of the helmet.
I believe that having the articulation makes that part of the head less protected.
Articulation also seems to be somewhat difficult to manufactur.
So what could be the advantages of having articulated cheek flaps.
