Speed away on your bike or hit the bag in the Under Armour Women's Infinity Medium Support Sports Bra. The 87% polyester and 13% elastane construction is built for medium-support activities like cycling, weight training and boxing. The molded, PU-injected 1-piece padding offers support and comfort, and the mesh panels encourage airflow. The adjustable straps provide a locked-in fit, and the material wicks sweat away for a dry workout.
