Not all helmet fit all head comfortably so important to try try and try, must keep helmet on for good while to get real very good feel of the helmet.
I live in a small town and could not find a dealer that had a Nolan N104 to try on. I took a chance and ordered one on the internet. I had to return it. It was very well made and would have been fine except the top of my ears were being rolled over and was uncomfortable. Cherie is right. If you cannot try it on before you buy it, don't buy it. I will stick with my HJC IS-33 helmet.
