Very nice looking helmet, but a bit on the small side. I usually use 57/58 and purchased accordingly, but if I would buy again I would go one size up as I had to stretch the inner space a bit to get a comfortable fit.
Excellent helmet, but needs brake in. At least for my head. (18.10.2022)

Compare to my C3 pro no significant difference in performance.
Pros: larger field of view, better pinlock, nicer exterior finish, 145 grams lighter-because of carbon. I have not noticed is quieter, I'd say about the same noise level. Cons: The ventilation system seems to be weaker than C3 pro. The C3 pro was comfortable strait out of the box, the C4 pro carbon needs to brake in at least for my head shape. I would give 5 star if it was comfortable from day 1.
