So I've tried on a load of helmets in the shop and owned a few different ones and it seems like I've got a really wide head. My head isn't very large, on paper I should probably be a S/M in most helmets but all the ones I've tried on squeeze above my ears. This isn't very comfortable and I end up getting a headache once I've had it on for more than a few minutes. But if I try wearing a larger size I have to adjust it down as small as it will go and then it wobbles about and covers my eyes. Not ideal.
I've tried on most Petzl and Black Diamond models as well as the Mammut Wallrider.
Has anyone else had this problem? Any suggestions on different helmet models?
