MATT, SUPPORTIVE TIGHTS WITH WIDE WAISTBAND. With a wider waistband than before, the matt Nike Speed Women's 7/8 Running Tights wrap you in a supported, locked-in feeling that's smooth and comfortable. Flexible support: Nike Power fabric provides a range of stretch and support to help you power through whatever your sport demands, while flatlock seams help prevent chafing and feel smooth on your skin. Reduced bulk: split hems at ankle open to enhance airflow and range of motion. Their zipper-free design means less bulk while you run. Media storage made easy: a drop-in pocket at the left hip stashes your phone, while an additional easy access pocket secures small essentials as you run.
