I have a Swartwool balaclava which fits loosely. I love it. I have a tight fighting one that is ... well I don't even remember what it's made of cause I probably haven't worn it in a couple years. Loose fitting is very comfortable for me. The helmet keeps it close to your head, easily tucks into my collar under my jacket. Seem to remember that my glasses fogged up constantly with the tight fitting hood, but not with the loose one.
