Cool Guzzi helmet. Fits a little on the tight side. I usually wear an L and with this helmet, both the XL and the L fits me, but the L is a little tight. Might loosen up with use though. 

Apparently, this helmet was not intended for use on public roads in North America. It's sold in Europe, though and they are a bunch of safety freaks there (no offence to my European friends), so I don't really understand. At any rate, please take this under consideration when purchasing.

Also, sorry, no returns on helmets.
