I've been trying to come up with a sizing chart for the Mk6 for the last couple of months and it appears that my Google-fu is not up to the task. I did a search here and out of 15 pages of hits also failed.
Is there a difinitive sizing chart for the Mk6? I've seen lots of discussion on hat size vs helemt size but none seem to agree so I can't even compile a guesstimate list. Does anyone here possess this information?
