Okay, so I have a big head... I have a really hard time finding helmets that fit (especially full face helmets). On my SERK, I run a half lid and have tried several different lids -- all XXL -- before I found one that feels okay. The trouble is, on long rides, and especially in hot weather, I get a really bad headache from the helmet squeezing on the sides of my head just above and forward of my ears (where you feel the muscles move when you open and close your jaw). I've decided that if I can find a good company that makes DOT approved custom fit helmets, I'd spend the coin. The trouble is that I can't find one. Do they exist?
Thanks,
Steve.
