I like their garb, but those arrows look like SCA blunts. SCA guys were helmets with grills to prevent that! Reminds me of playing paintball back in the late 80's with my buddy. We both had pump guns & goggles without mask. I was defending a fort, he popped up from the side of a bunker and I was expecting it and POP right in the nose from about 10 feet away. He went down. His face was covered in red because it was a red paintball. Anyhow, next time we played we both had face masks. (Mine learning point came from a paintball to the corner of the mouth)
I guess if someone were worried about the face playing Dag/bel, they could get a paintball mask or one of those jason masks and paint it up. It wouldn't be armor but it could protect your face if you were worried about face hits.
