from this site of goodness :

As an eccentric approver, I delight in hats as an idea, but in practicality when ever I have worn them, their tends to be an element of pressure and sweat where brow and hat meet, and underneath a volume of stagnant hair not getting its quotient of fresh air. I really do approve of them I really do, theyre more characterful and fun. I guess perhaps they could do with a lightweight comfortable breathable re-invention with modern materials. But certainly … if you hair has already taken leave of your head, then hats to me seem a wonderfull idea :)
