One thing first: the fit of a helmet is always ne individual thing. But in this one, the adjustment is simply very good. I had previously NEN 661, has only worked at the back of the head setting. When IXS a band goes completely around the head, which can be adjusted by the dial perfectly on the head. There are still some other helmets, where this is so resolved. Very good is also that the helmet protects the neck area well because he has moved down.
