I usually wear something on my head...the hair went away years ago, and the sun is dangerous year around at 6000 feet. Most often a crusher"cowboy" hat or a baseball-type hat from my favorite microbrewery. When it's cold out, I usually wear a "cap, watch, wool, black" (that's what the tag inside says) and, for summer hiking, one of these with a bandana stuck under it in the back for the Foreign Legion look.
