This is a great shirt. It fits well, looks great and does its job. I have 3 of these shirts!
The Nike Power UV crew has a pretty simple but classy design. I really like the oblique stripes on the side. The color combinations are a success, especially with the Nike shorts (that usually match the stripes; in that case, the light armory blue shorts). I usually wear large, but went for medium size for a snugger fit (since I wear these shirts mostly at the gym).
