A hat is a necessity for me because of the relative absence of hair and skin cancer issues. Having a Sqaumous Cell Carcinoma removed from the top of your head ain't no fun.

I wear a black balmoral with red and white dicing with the kilt, a ball cap in the summer, a flat wool cap in the winter and one of those little roll-up wool bucket hats with the short brim in a black watch tartan for the cold rainy winter weather.

Paco, thanks for the link to Tilley Hats, I'm going to look into one of those for summer, I think it will do the job for me.
