Portis in spot-on there. Lou has made a majority of my winter cycling clothing.
Why not just stop in at an REI, Sports Authority, Dunhams, etc and try some on instead of relying on the internet? My first balaclava I purchased when I weighed almost 400lbs (below 300 now) so you could say I had a pretty big head, and it fit me loose at the time. Cost me less than $20 at REI and I'd still be using it if I hadn't "undergrown" it.
