The Nike Dri-FIT ADV Visor is a running visor that shields the most important parts of your face while keeping you feeling breezy and cool. A DRI-FIT ADV sweat wicking band manages moisture, and vent holes around the crown aid in keeping your head dry and cool. The shortened AeroBill reduces the suns glare on your eyes while staying just out of sight, and an adjustable back strap design lets you personalize your fit.
