Just as cycling equipment benefits from the feedback of the sponsored male racers, the gear used by the growing number of female cyclists reflects the hard-earned knowledge and feedback that pro women can give. The input of ladies sponsored by Castelli has led to this uniquely cycling-specific sports bra, the Castelli Rosso Corsa Light Bra.
Cycling in particular demands slightly different things from a bra than running does. Chest-crushing compression is less of an issue, so the Rosso Corsa Light Bra focuses more on breathability and ventilation. Sport bras can become quite soggy when you're really exerting yourself, and then you're stuck with what feels like a sweaty straightjacket wrapped around you for the duration of the ride. This is a problem (particularly in winter weather) when you're riding over multiple long climbs where you're sweating on the way up and freezing on the way down. This bra has been designed with an ingenious mix of tech fabrics, which are all intended to provide the optimum amount of wicking to keep you comfortable and dry. The sides and back have maximum ventilation with the Tulle Mesh inserts in place to help ventilate.
That is not to say that Castelli has compromised on fit and support. The Rosso Corsa offers gentle support and a comfortable fit. In particular, the cross straps are Giro 3, the same soft, stretchy material and seamless design used in Castelli's top-of-the-line bibs. As a result, you get less stress and fatigue on your shoulders and trapezius muscles on a long, demanding ride.
The Castelli Rosso Corsa Light Bra is available in either Black or White. The bra works best for A/B cups, and comes in five sizes according to the measurement around the rib cage under the bust: X-Small 26-28in, Small 29-30in, Medium 30-32in, Large 32-34in and X-Large 34-36in.
