The Castelli Rosso Corsa Bra has mesh inserts for excellent breathability, moisture wicking. The ultra light fabric stretches and moves with you. The back hook-and-eye closure has 3-position regulation for simple wearing and removal. The shaped cups give you full coverage and support, while contoured seams and underbust elastic gives an excellent fit. Meant for cycling, this is not supportive like a sports bra for jogging. Available in White and Black.
