Nike Therma-Fit Sphere Headband Black/Silver, One Size

The Therma-FIT Sphere Headband covers the ears for cold-weather runs where a full hat would be too much. Nike Therma-FIT technology traps heat while wicking sweat away, so the headband stays warm without holding onto moisture. A stretch blend of polyester and spandex fits a range of head sizes, and flatlock seams keep the inside smooth against skin.
