Castelli Free Aero Race 4 Team Womens Cycling Shorts


The Castelli Free Aero 4 women’s cycling short represents a significant evolution from Castelli’s previous model, their best-selling short ever. There's a new leg gripper that still features a lie-flat raw-cut edge but now has vertical silicone stripes to keep it in place without restricting stretch. 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, minimised weight, and leg grippers that don’t cut off blood flow to your muscles. It has women’s-specific fit, front construction, and Castelli’s women’s Progetto X2 Air Donna seat pad. 


  • Vortex dimpled fabric on legs for aero performance
  • Forza fabric on inner legs with 38% Lycra® content for perfect fit
  • Giro Air mesh-like leg gripper elastic for better grip distributed over larger area
  • Flat-lock stitching
  • Reflective detailing on back
  • Women’s-specific Progetto X2 Air Donna seat pad for even greater comfort
