I'm probably the last person that should be posting on helmets, but having said that. Carbon Fiber helmets are top of the line. They are lighter, means less stress on your neck and more comfort on long hauls, they are stronger, that means more protection, that's what you buy a helmet for, also they are thinner so you don't look like a bubble head while you're riding. Fit is very important, go some where they have a good sales person that can make sure the fit is right, not a sales person trying to get rid of old inventory. If comfort, safty and style means anything to you, go for it, why wear anything less? Now get input from forum members that own them and wear them, I'm no expert because I don't wear helmets.
