Without compromising the warmth you love, the Nike Dri-FIT Element Top has added a whole new level of breathability with a back mesh panel. Coverage is king, though, with this new iteration: The improved collar is a little stiffer to help cover you in windy or cold conditions, and the longer back hem and thumbhole design give you something extra to keep you comfortable on your run. Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable. Thumbholes help keep in warmth. A Half-zip design lets you adjust your coverage in changing conditions. The high collar provides warmth and coverage. A longer back hem extends coverage. 88% Polyester, 12% Spandex.
