SWEAT-WICKING, BREATHABLE TANK. The Nike Pro Tank is made with soft, sweat-wicking fabric to help keep you dry and comfortable during your workout. An open-back design lets you show off your sports bra while letting cool air in when your routine heats up. Quick-drying design: Dri-FIT technology moves sweat from your skin to help you stay dry and comfortable. Cooling comfort: an open back with mesh panels lets the air flow freely to help keep you cool during high-heat sessions. Extended coverage: slightly longer length helps keep you covered while you bend and stretch.
