I'm beginning to look for a helmet, autox only right now. My problem is that I like to have my hair back off my face when I'm in a helmet, sometimes in a ponytail/thrown up (when it's really hot) and other times down is fine as long as it's out of my face. The problem seems to be that my hair's thick enough that putting my hair up makes me go up a helmet size (to fit correctly as well as not be super tight). Should I get a helmet that fits when my hair's down and just deal with it being too tight when my hair's pulled back? BTW, did anyone else have a little trouble finding a helmet that's not too big (ie, some only come in med, I'm usually in a small)?
