Nike Pro Dri-FIT Short Sleeve Shirt for Older Kids (Boys) If the design of this top was a science project, you'd get an A for it. Here's why: We studied where athletes sweat so we could apply our sweat-wicking technology where it's needed most. The result is a smooth, stretchy, lightweight top. So you stay cool and dry when you train and play. Nike Dri-FIT technology draws sweat away from the skin, allowing it to evaporate faster for dry comfort. The knitted material feels soft and supple and the flat seams ensure a high level of comfort.
