It appears you might consider picking and choosing among all of the above recommendations. My choices: a large VENTILATED wide brimmed hat (good for top of ears, nose, back of neck and particularly good for those of us challenged with a lack of natural scalp protection); I vote for short shirts and pants, light in color because they tend to be cooler; SPF 30 applied thoroughly and several times a day to all uncovered areas, and don't forget Jack's input that it goes on lower areas to protect against sun bounce off the salt. Today?s sun screens allow us more latitude in apparel than in the past, IF WE FOLLOW THEIR RECOMENDATIONS.
