Wearing hats all day long?

Hi,





I wonder how some people wear these all day long? Things like these: http://www.thegreenhead.com/imgs/pistil-...





I am guessing these are special ones that lets air in, unlike the ones for cold? Doesn't it cause overheating and itching?





Also where can I find these kind of hats? Preferably ones that doesn't have stitch marks so it would look totally round on the top however you wear them.











Thanks.

im sure those hats are hot to wear all day but ppl wear them cuz they think they look "cool"
Reply:maybe a lot fo people that these hats have shaved their head and dont have hair so it doesnt cause over heating or itching.
