The team wears this polo. Max comfort and the collar doesn't bug you while you play like most other polos. Really breathable and sophisticated style while on court.
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).
