Sports bras should not be complicated. They should be comfortable and provide support. So Under Armour got to the root of the problem and asked women how their favorite bra could be improved. And lo and behold, it worked. The Armour Crossback Mid offers strategic support for medium-impact activities like cycling, weight training and boxing. The super supple, double-layer HeatGear fabric gives a next-to-skin feel. The lightweight fabric also wicks away sweat for dry comfort. The crossover straps with modern keyhole detail and elastic underbust band with UA logos provide an optimal fit. The removable bra cups are soft, quick-drying, and feature perforations for breathability. Plus, with helpful right and left arrows, they're easy to put back in after washing.
