OPTIMAL HOLD, EASY TO PUT ON AND TAKE OFF. Start low, go higher. The Nike Dri-FIT Swoosh Zip-Front Sports Bra takes a classic design to a new level with a fabric made from at least 75% recycled polyester fiber. It's easy to put on and take off, and the semi-automatic zipper prevents accidental opening. The breathable mesh on the back ensures cool comfort. This gives you a secure fit for all your reps, steps and jumps. Easy on and off The semi-automatic zipper on the front prevents accidental opening and still allows for easy on and off. It stays fixed when you push it down but is easy to open. It also features an internal buckle that doubles security. Cool and dry Nike Dri-FIT technology wicks sweat away from the skin, allowing it to evaporate quickly for dry comfort. The back features mesh material for breathability. No empty cups Stretch fabric and an elastic chest band ensure a comfortable, snug fit and prevent empty cup feel.
