good one on "catching when looking over your shoulder".I wanted one but read its a great addition for high speed run but causes too much interferrence ( catching or rubbing)when looking side to side.
i returned my HJC carbon helmet because i read the chin catches onto your shoulder when looking over. the "carbon" model extends in the chin area out more than other lids. having it at my house i checked and it does.
the look of the hump is wicked though
