It's almost time to pay off all your training in the Bank of America Chicago Marathon, 1 of the year's biggest races. This 1/2-zip running top sits slightly off the body, so you can wear it alone or as an easy layer when it's go time. Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable.
Cool Control A 1/2-zip design lets you adjust your airflow and coverage. The collar has fewer seams for a smooth feel. Extended Warmth Thumbholes let you extend your coverage and help hold the sleeves in place while you move.
