Had a bleeding little hole in my head after a fall the other week. First time that's happened in twenty years, but I have a kid now and don't wanna take that risk. But goddamn do helmets really HAVE to be that thick? I don't mind slight concussions or stitches, all I want to avoid is being a young dad in a coma. What about thinner helmets like the one that soccer goalie Petr Czech was wearing after his skull fracture? Any expertise/advice much appreciated
