I bought this in two different color for my husband. He takes turns wearing them on weekends to go to our son's baseball games and not have to worry about the dangers of sun poisoning.
I purchased several of the fitness shirts, for bike riding & they are excellent. Perfect in every way. The lime green is also great for safety, it stands out. But, also like the benefit of sun blocking, cool fabric!
