The Castelli Rosso Corsa Support Bra is specifically designed to keep moisture at bay. The fabrics used help to constantly wick moisture away from your skin to the surface for quick evaporation. To speed up this process, Tulle Mesh is added at the sides and back. To ensure support, the Rosso Corsa is designed to support without constricting. The Giro 3 fabric used on the cross back won't dig into your shoulders, and the eyelet hooks at the back adjust to the perfect fit. The Rosso Corsa is recommended for CD cups.
