Being in the sun can be lethal for me. I bought the long sleeve, 50 spf Tropicwear shirt as soon as I saw it in the catalog. Recently, I attended an outdoor graduation party on a hot, bright, sunny day. The shirt kept me cool and comfortable for several hours. It wicked away the moisture and deflected the sun all day long. It's a great shirt and I would recommend it highly to anyone who is in the high risk category for skin cancer.
