The Under Armour Protegee Sports Bra C Cup has a zipper front that helps prevent that dreaded over the head stretch out and the sounds of fabric and seams popping that goes along with it. While the zipper brings the front together, the hook and eye closure adds an extra measure of security. The four way stretch fabric works just as hard as you do, keeping you comfortable longer. The Moisture Transport System treatment and antimicrobial technology keep unwanted moisture and odor away from your skin. Designed to give you high impact support, this bra's racerback style gives you increased range of motion.
