The Under Armour Women's Crossback Mid Impact Sports Bra delivers strategic medium support for cycling, weight training, boxing and other mid-intensity activities. Updated with a sleek crossover strap design and keyhole detail for easier on and off, it's built for performance without sacrificing comfort.

Soft, quick-drying moulded cups offer extra structure and coverage with perforations for added breathability, while an improved interior construction keeps pads securely in place — during wear and washing.
