Every detail of this short is made for racing: muscle support, aerodynamic fit, comfort to let you concentrate on wringing every last bit of energy from your legs, minimized weight, and leg grippers that don't cut off blood flow to your muscles. Even the printable spaces are optimized to keep your sponsors happy. The women's version of this short is the closest Castelli comes to a sized-down version of the men's short. That's intentional because this is made for women racers, with the emphasis on the racer part. It has women's-specific fit, women's-specific bibs and front construction, and Castelli's women's Progetto X2 Air Donna seat pad. Castelli's test crew has naturally included some non racers, and the first thing they comment on is the extreme comfort. This will be your go-to short even when you don't have a number pinned on your jersey.
