I read somewhere that Giro is the most popular helmet worn by cyclists, which is followed by Bell, and they happen to be owned by the same parent company. But I digress...I have gone and tried on many a Giro helmets in varying sizes. My hair is too thick to pull through. Scary huh? Sometimes, I wish I could go back to my college days when I wore it as a pixie cut, but I like having long hair.
I think that there is a LBS that carries Rudy Project helmets. I may go try some on next weekend...
