I'm fair-skinned and burn easily. A friend recommended buying a swim shirt. I did not know such products existed and I was concerned about this type of clothing causing mobility problems when wet. I bought this shirt prior to my trip to Antigua, West Indies. I was very glad I did. I wore this shirt snorkeling, swimming and sailing. It is light weight and dries quickly. I hardly knew it was there. I plan on using it whenever I spend a day at the Lake Michigan beach.
