Indeed
The problem is some borderline case. Fits decent at the shop but not after 1 hour of using it. It's incredible difficult for me to get a helmet to fit as well, as I'm borderline S and M size. New M might fit well but loosens fast after 6 months of wear like my MT Atom.
HJC and AGVs tend to be more on the slim size, so in my case the Rpha 70 in M fits perfect. The same HJC F70 in M don't fit at all despite supposedly having the same head shape.....got real uncomfortable in less than 10 mins.
My Zeus in M size on the other hand is a bit loose on the crown but insists on shearing off my ears every time I need to take it off.
By right , you should put on the helmet and go sit on your bike...so you'd be able to also check if the viewing angles all work with your riding position. Nothing is worst than a helmet that restricts shoulder checks or a brow that is too low/thick that you can't see overhead traffic lights.
I can imagine the pain (pun intended)
downwards compression pain is hard to detect when helmet testing
even same helmet, different unit can have variation despite best effort of coming out the same mold, fact is, plastic can deform due to internal stress
for the Zeus, are you with balaclava? when I wear glasses, the balaclava works to reduce glasses vibration, and saving the ear when removing the helmet.
I find AGV more narrow, but only tested the K1 IIRC
eyeports are designed for different riding styles, I look for helmets with good upward viewing angle.
