I've had this helmet for a year and a half. My third AFX helmet. Helmet fit varies by manufacturer based on your head shape. AFX helmets seem to fit me well.
As far as the helmet itself goes - I'm pleased with it. The quick release and the drop down sun shield both work very well. I wear perscription lens the shield is great. The quick release strap is a problem if you want to lock your helmet to the bike.
