Incredible quality by Nike in their hi-wick Dri-Fit Series! Dri-Fit features advanced wicking performance developed for active individuals. Specially formulated hydrophilic polyester fibers move heat generated body moisture away from the skin to the outer surface of the fabric. This aids in rapid evaporation, keeping the wearer cool and comfortable. These fabrics can be used for leggings, jeggings, shorts, tops, bikewear, and other workout wear.
