The inside of the leg is made from Affinity Pro Lycra that offers excellent stretch and rebound for comfort. Vortex BLC textured fabric is used on the side of the legs for improved aerodynamics, and the GIRO⁴ leg grippers hold the bottom of the bib shorts in place – two features lifted straight from Castelli’s pro peloton tested Free Aero Race 4 Bib Shorts.
