I purchased my new Tilley TH9 hemp hat because my old cowboy hat had bitten the dust.  I was hesitant to buy a hat made of hemp because I didn't know if it would be too hot in the desert heat of Utah.  I have been wearing it every day on my two hour walks with my fox terrier and so far, it has been a great hat.  It shields most of my face from the sun and feels cool on my head.  When I wore it to work one day, I received many compliments on it.  It is a very good looking hat and I love the three different colored hat bands that you can change out to match your mood.  I love my new Tilley hat and now I understand why everyone raves about this brand.
