Mask fits well. I have a pretty large head (23.5") but this is not tight or loose. The mask covers the front of your face back to most of the top of head. The sock is heavy duty and gets quite warm quickly. I think I'll buy another just for winter wear! Wish the eyes had a blackout screen installed. The sock is long enough to cover my neck. Very detailed, but i can't reliably make the jaw move. Takes acrylic airbrush paint well for custom looks.
