This NikeCourt AeroReact Rafa Top helps keep you cool when your match heats up. Nike AeroReact technology uses fibers that open when you sweat, then close as you cool down, helping you maintain the ideal temperature. It features an allover diamond pattern that enhances breathability and mimics the design of NYC sewer covers. The zigzag design on the sleeves is inspired by the fire escapes found throughout the city. Both comfortable and stylish you may find yourself wearing them on and off the court.
