I love my Suomy Gambler 2 or Goorbergh!! It's very hard to find Suomy's to try on. I know WOW Motorcycles used to have a couple to try on. Generally Arai's and Suomy share the same head size. Also you can change the padding to adjust the size. The XS, S, & M all share the same outer core. Then the other larger sizes share that outer core.

You won't be dissapointed w/ Suomy. I absolutely love mine.
