Arai seems to run a little small in compared to Simpson. If I had gone by size charts I would have got too small a helmet.
Now the controversial part for some... There is no place close try a GP6. Looking on ebay, you can get a great deal on Arai's via Japan. So I took a chance on a buyer with a long history and that had recently sold this particular item. Ordered it midnight Thursday and it was delivered Tuesday, $590, including $60, in express shipping.
SAH2010 and FIA sticker as you would expect, it just has Japanese only instructions.
