Nike Men's Pro Sleeveless Compression Top The Nike Pro Top hugs you in lightweight fabric with breathability built into heat zones to keep you cool and dry from warmups through cool downs. Stretchy fabric made with at least 75% recycled polyester fibers comes in a tight fit that easily layers under other tops. Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable. Mesh over high-heat areas at the back and sides lets air flow to help keep you cool when the action heats up. Flat seams feel smooth and make it comfortable to layer under other tops.
