I like to garden and while my intention to put on sunscreen before I go out is there, my follow through isn't, so several sunburns later I found this hat.  It has a long but flexible bill, like a baseball cap, the mesh on the sides really does keep you cool while providing shade for the sides and back of your neck and the top of the shoulder blades.  I have a small head so being able to adjust it is awesome.  It looks a little safari-ish and it took a few hours to get used to it flapping occasionally in the breeze but it also makes you look like a career outdoorsman which I'm not but like to pretend that I am.
