Now faster and even more comfortable, the Free Aero Race S Women's Bib Shorts are made from stretch fabric, engineered in the wind tunnel to deliver a 3% decrease in drag as you ride, for a race fit without restriction. They bear the Rosso Corsa label, Castelli's stamp of prime racing quality, and come in a range of colours. Built around Castelli's best, pro-level women's seat pad with progressive damping and reduced seams for long-distance comfort and featuring grippers to keep the legs a in place, along with barely-there mesh bib straps that allow air to circulate freely, they include a race radio pocket and 50+ UPF sun protection.
