Sorry if this has been posted before, but a search for "Helmet Fit" didn't yield much. I went to a local shop, recommended by a friend who rides. I was measured and tried on a few helmets. My headsize is 59cm. In the Arai helmets that means I am at the lower end of the spectrum for a size Large helmet. I tried on a size L XD3 and it felt .. bad. It was very tight. I only wore the helmet for a few minutes before taking it off due to a headache coming on. The cheek pads were very tight as well. I've seen photos of folks wearing the XD3 and XD4, and its pretty obvious that their faces are getting a good squeeze from the helmet, but beyond that, the cheekpads on the helmet I was trying were pushing in below my jaw line to the point of choking me. Think of how it feels when a doctor feels on your throat when you have swollen tonsils. Now imagine the doctor doesn't like you. That's how tight it was. How snug is "snug"? Should the helmet be uncomfortable when you first buy it and let it break in? Should it be "just right" on the day of purchase? I tried an Arai XD3, Icon Variant and a Scorpion street helmet. All of them felt to tight at my size per the helmet manufacturers listed size guides. I'm going to try and find a shop that carries AFX helmets so I can give their DS helmet a try. Thanks for any help and advice.
