This may sound like a faintly dim question, but as I'm a faintly dim person that's probably understandable.

I've just got myself a Panzer Crewman's M43 skicap, and one thing that's always puzzled me is what the point of the buttons on the front are. They seem to connect two pieces of cloth that run around the sides of the cap, but as far as I can work out, if you undo them, you just end up with a fairly useless bit of cloth around your ears.

Was this actually designed to create an additional layer of warmth for winter conditions, or was it just fancy design?

Cheers,
