Lidpicker "Process"
A good process to sort out whether your head is round, long oval or whatever, which allows you to totally dismiss certain helmet types. The system totally falls apart when trying to figure out L, XL XXL. For over 25 years helmet manufacturers' measurements tell me M to L.....and those sizes don't even START to go over my head. That leaves me with the process of finding the helmet somewhere close by to try on....then shop for price, and look for recommendations by other riders. So....overall, "LidPicker" was a gamble, and I lost....but got some $ back with the $15 credit.
