The Brooks Women's Sport Dare Crossback Zip bra has a hidden bottom band design that fully integrates the support in a chafe free design. By combining technologies Brooks have created a distraction free design. The DriLayer HorsePower fabric is supportive and sweat wicking for a fresh comfortable feel and it works alongside the moulded cups and free-cut construction for visible shape and a streamlined silhouette. Strategically placed ventilation helps to improve air circulation to keep you comfortable as the miles pass.
