You definitely need to wear a T-shirt when snorkeling if you burn easily. Many snorkelers and SCUBA divers wear T-Shirts. But, you also need to apply a high number sun block before you put the T-Shirt on. We have seen people on cruises that actually had the logo (on the back of the T-Shirt they were wearing while snorkeling) sunburned onto their back. Not only that, they were in a world of hurt! Don't forget the aloe vera gel or something that will relieve sunburn just in case.
