With a wide waistband for comfort, the Nike Speed Tights wrap you in supportive, stretchy fabric. Ruffled side panels help ventilate your stride as you push through the mile. Nike Power fabric provides a range of stretch and support to help you power through whatever your run demands, while flatlock seams help prevent chafing. Mesh-lined drop-in pockets in the waistband tuck away the important things. The left secures key cards while the roomier right side can hold your phone. Dri-FIT technology helps you stay dry, comfortable and focused. An internal drawcord in waistband lets you customize fit.
