Since I shave my dome, I usually wear a hat. In the past it has been a Guiness ball cap. I also on occasion wear either a herringbone wool Irish styled hat, but it is very hot during the summer months. At this summers Potomac Celtic Festival, I opted for no hat with a lot of #70 sunscreen. I came through that one in good shape (no sunburned dome), but it was a bit inconvenient refreshing the sunblock several times during the day.
