Because most guys know there is no answer they can give you.Thanks! Everyone else seems to think it doesn't rate an answer. Don't know why.
Each helmet fits each person differently.
Every persons head is shaped uniquely. What fits Rider A

it's the right size.
I ride with an AGV Demon Top Vent because it fits my face the most comfortably.
