Size Large i was convinced to buy a large, the large is soo tight that i get headaches and can't wear the helmet, i tried to return the helmet but they had a 24hr return policy on helmets so that of course didnt work. i went as far as to buy smaller cheek pads but that didnt do it, the helmet was then passed onto my wife but it was too large for her to use safely. i i paid $750 for the helmet and would like to get $300 for it, it has only been worn for maybe a total of 6hrs and is like new. still have the package with the stickers and the extra screws for the visor, i did stick the anti-glare sticker on the inside of the visor. pictures were taken today as i have had to buy my wife a new helmet that was safe, and nobody will be using the shoei and it is too fantastic of a hemet to sit on a shelf.$300 is what i would like feel free to PM me an offer if you think that is too high. i live in Cranbrook but can arrange to ship.
