It fits my head very well, I wear a small helmet so that helps. I use my Harley as my daily commuter. First night I wore it home it was 33 outside and for the first time my chin and neck was warm. It has been at or below freezing here since I it got here and it has kept me warm the whole time. I wear it up to my bottom lip which is high enough that it seals to my helmet to keep the wind out. I could see having 1 improvement on it, if it had the same wind resistant material on the front of the neck like it has on the chest you would never know it was cold outside.
