Start low, go high. The ideal layer for just about any workout, the Nike Dri-FIT Swoosh Zip-Front Sports Bra takes the classic design to the next level with fabric made from at least 75% recycled polyester fibers. Easy On and Off The semi-auto lock zipper on the front helps prevent unwanted unzipping yet still makes it easy to get in and out—it stays in place when you press down on it, but zips up easily. It also has an inner buckle that doubles up on safety. Cool and Dry Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable. The back side is made of mesh to let your skin breathe. No Empty Cups Stretch fabric and an elastic chest band provide a comfortable, compressive feel while shaping to prevent the sensation of empty space in your cups.
