A sun protection shirt may sound ridiculous when you are enjoying the sun, sand and sea. After all, we live in a society where being almost bare is an accepted part of the popular culture especially at the beaches. But this is where you are wrong.
The sun is most intense at the beach for many reasons. For one thing, the surface water of the sea significantly reflects the ultraviolet rays so much so that, even if you were in the shade, your skin will still be affected by them. For another thing, your complacency about your nakedness and your youthful body will blind you to the imperative need to cover up with some type of UV clothing.
