The phrase "too much of a good thing is bad for you," is true for a lot of things (like sun exposure and harmful UV rays), but UPF isn't one of them. Not only does this tank have a high neckline to shield sensitive areas, it has a 50+ UPF fabric, which is the highest ranking in the game. That said, go out and do a lot of what you love to do. Definitely nothing wrong with that. Features: High-performance solar knit with 50 UPF fabric Forward-angled side seams Racerback Shirttail hemline
