I got this helmet to replace my top of the line UVEX which replaced my top of the line Giro. This helmet is the best by far. I wear a size medium in all 3! And you have got to love the reflective strips on the Mavic!
I am not Asian; in fact I am as pasty white as they come... my wife refers to me as plain white vanilla (I am not sure if that is a compliment). Anyway, though I stand 6'1" and weigh 175 lbs I have a smallish face and find Oakleys are generally too big. These fit great and look good too... and most importantly they have the legendary Oakley optics so I can see EVERYTHING!
