The Castelli Free Aero Race 4 Short is very fast and designed for cyclists who feel restricted by bib straps. In order to find the right combination of fabrics and the right construction, Castelli used wind-tunnel testing and pro rider input to make their classic fast race shorts even faster. Through extensive research, performance level fabrics and their locations have been tweaked for that extra advantage. The Vortex dimpled fabric pulls in air so a rider slips through the wind with no clothing getting in the way. As a result, drag is decreased and air circulates to make a racer faster and keep him dry despite heavy sweating. The smooth Forza fabric on the inner leg doesn’t rub against the seat making the bib-shorts durable. Castelli’s Progetto X² Air Seamless seat pad is renowned for its protection, softness and lean construction. The seamless skin layer is about as soft as a surface can feel. In addition to its softness, the Progetto is the fastest seat pad raced in by Castelli’s sponsored pro-riders. Castelli used the minimalist philosophy to design the Progetto seat pad; thick padding is only used where absolutely necessary for comfort. Perforated viscous padding is placed under the highly sensitive ischial and perineum pressure areas. The padding then thins out so a cyclist doesn’t ride on a bulky seat pad. The skin layer surface is seamless and exceptionally soft while it is also well ventilated to keep a rider dry.
