If you turned this top into a science project, youd probably get an A. Heres why: we studied where athletes like you sweat so we could apply our sweat-wicking technology where its needed most. The result is a smooth and stretchy lightweight top that helps you stay cool and dry during training and play. Benefits:Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable. Knit fabric feels soft and smooth while flat seams resist chafing for comfortable wear.
