This is a great discussion, but not enough about fit. Jess mentioned the front-to-back length rather than the side-to-side. I guess I also have an oblong head. I wear Arais 3/4 now, but they are very uncomfortable on long rides due to a bad fit. They feel good on the sides but are too tight on the Front-to-back. After a while, the pressure on my forehead gets too uncomfortable. I need a longer and narrower fit. Anyone else have this problem?
Funny... I have both a large and an extra-large Arai, but can't realize much of a difference between the two... go figure!
I once read an article that discussed the phenomenon of the two essential shapes of the human head (round/symmetrical and oblong), and which identified the major helmet mfrs which made helmets for each. I did a little looking and I found it discussed in other forums, but cannot find the article.
I had a bell magnum I wore for years, and it was a great quality helmet, but after 2 hours I got bad headaches, because it was too tight front to rear for my oblong head. I had no money so I wore it for years.
I can buy about anything on-line and get a decent fit (except some Chinese larges are really smalls).... except two things Helmets and Boots. I drove around until I found the new Scorpion exo100 and tried them on. Thou the U-tube suggested they ran large, I had to go up from a large to an XL for a good fit (7 3/8 hat). What ever helmet you get, I think you have to drive around and try them for a good fit.
On the Scorpion being hot, I will say it is the best full-coverage half I've ever seen, meaning is sits lower on your head all the way around than other halfs, and it has full DOT thickness for protection. It is a big half, and it likely does get warmer than other much smaller halfs, esp those not set up to take a full warm neck curtain for cold weather. But the fit/comfort for me was best ever. And my head sweats in all halfs in hot weather so it is not an issue for me. What I like is the whole liner can be snapped out and hand washed or in the machine on delicate, with a shot of fabrese, so it doesn't smell like
Eau de Horsesweat permenently. Plus I ride with mine year round in the coldest weather, with the neck curtain and underarmor coldgear hood.
Cheap bastard that I am, I cut my own hair. Come summer I lose my Air Force 1/4 inch hair, and go to a Marine boot buzz cut so am cooler. (temp wise, not looks wise, there's no help for me there and I don't care a bit) My chin hair is somewhat longer so I can remember what I had for lunch.
Oh, and last week my buddy was diddling around with his bike and managed to spill his large coffee fully into his inverted helmet. I found this extremely amusing (as he was pouring it out saying bad words)..... but he did not.
