Now faster and more comfortable, the Free Aero Race 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.

Part of Soudal Quick-Step's kit and available in a range of colours, they bear the Rosso Corsa label, Castelli's stamp of prime racing quality.

Built around Castelli's best, pro-level seat pad with progressive damping and reduced seams for long-distance comfort, and featuring grippers to keep the legs in place, along with barely-there mesh bib straps that allow the air to circulate freely, they include a race radio pocket and 50+ UPF sun protection.
