I bought this after trying on a friend's.  I LOVE the look, first of all.  But immediately after putting it on -- I was stunned by the "airy" feel of the hat.  This hat is the best ventilated hat I am aware of.  Not only does it provide fantastic coverage of your face and neck, but the part touching your head is mesh -- so that even on the hottest day, you can have a nice breeze across your pate.  Absolutely fantastic hot weather hat!  I have two of them.
