This is almost like a golf polo. It's a bit more low-key than most Nike tennis apparel but I love it. It's perfect for public part tennis, when you don't want to "overdress". ;) It's very light, thin, well ventilated. It's more of a regular fit. Or size M, it fits almost like a L in the Sharapova collection. Since I have wide shoulders, I decided to keep it even though it doesn't have the extreme-fitted style.
