The Nike Sleeveless Tracksuit Top is versatile black jacket made from nylon with a mesh lining for comfort. The top features a 1/2 zip closure and pockets, making it perfect for casual occasions. With the iconic Nike logo accent, this windbreaker style jacket is size M but I wore this when I was a size 8 so would say it is a small (and with the Nike joggers I have listed too).
