I have started this year with the longboarding. After seeing the first accident on Youtube where rear heads rebound on the asphalt I ordered immediately the helmet. I have a very big head and had only the feeling that he does not fit so well. Have a few minutes with the various depositors experimented until it fits best and after I had this thing for a few minutes on his head he gave a sudden like a glove. Somehow, the helmet has adapted. Now feels even after a few weeks well and keeps super warm even on cold days.
