I relplied to your pm..not sure if that worked, so I'll try here too. A little new to forum discussion/pm'ng, usually just a lurker, lot of great info on this site. Since I'm new don't have anyone to vouch for me here. Would rather sell the helmet here than ebay though, as this seems like a pretty sweet site.
My fitted hat size is 7 1/4 to 7 3/8 which falls into the large category, helmet is adult large and fits great. Definitely a large helmet, total big mountain and bad ass looking. Would be great to hook you up if this is what you're after. Let me know if you have any more questions.
