Castelli’s Velocissima Women’s Bib Shorts are designed for long days in the saddle. From the supportive, low-profile KISS4 chamois to the Endurance Evolution fabric, everything in the Velocissima is made with long-ride comfort in mind. That Endurance Evolution fabric is a bit different than your typical spandex -it’s moisture-wicking and compressive, meaning it keeps your muscles in place so they don’t fatigue prematurely. This won’t result in the dreaded sausage-leg, though, due to Castelli’s intelligent patterning.
