]I would imagine playing while wearing a visor is more advantageous than wearing a cap as you're letting your head breathe, keeping cool and you avoid that cloggy, sweaty feeling you get with your hair if playing in very hot conditions. [/b]
I guess there is just a general consensus on the ATP tour that it is considered "feminine" as so any wta players wear visors now, which is sad of course.
I'm a guy and am comfortable wearing visors while watching tennis. AND I COLLECT them too
But wait..does exposing your crown on the sun triggers balding?
