Arai Concept-X Overland ヘルメット

High quality materials, excellent looks, comfortable.
However, considering the very high price and Arai reputation, there should be no flaws.
But, there are. The chin strap is positioned too far back so it presses on my neck and Adam’s apple. Plus, there is no padding on the strap, making it very sharp. So I had to put a padding from my cheap bycicle helmet!
Secondly, the ventilation is even too good, even when all vents are closed, there is still quite a lot of air going in, I am afraid it will be very drafty in colder months.
Third, the visor has a latch which is very difficult for opening, especially with gloves, and the opening is too stiff.
Otherwise, fit is as measured, I wear M and it is ok. Comfort also very good aside from the strap.
