I have a very small head (have a hard time with the length of sunglass arms because I am a pin head. So far the most comfortable helmet I have tried (tried Bell and Garneau) is a $40.00 Specialized helmet. It isn't the most stylish thing I have ever seen, what helmet is, but it fits my head very well and is pretty cool. Now if someone could just invent a helmet that doesn't give you helmet hair. I have medium length hair and no matter how I pull it back, I get a lovely crease in the back of my hair that won't come out till I was and dry it. Stupid hair.
