Just got my C3
Just got my new helmet yesterday. I ordered it last Sunday and I got it last night (Monday). Slow shipping but it was free so I can't complain too much. I wear a medium in Shoei and Arai and the C3 is the same. Medium is a perfect fit. I get a red mark on my forehead but there is no pressure so I think this helmet is going to work out great. I wore it around the house last night for over an hour -- comfy!
