Castelli Ineos Grenadiers Free Aero Race 4 Bib Shorts

The Vortex dimpled fabric on the legs stops air attaching to the fabric so that air slips by easily.

The leg gripper features a lie-flat raw-cut edge but now has vertical silicone stripes to keep it in place without restricting stretch and leg movement.

Castelli has completely redesigned the short's panelling to improve fit and support while also making the short look even cleaner. The bib straps have re-engineered the bib straps with new lighter, more breathable material so they stay cooler, lie flatter and are more durable. A new loop for a race radio microphone has been added at the request of team riders.

The Free Aero Race 4 Bib Short uses Castelli's pro-level Progetto X2 Air seamless seat pad, which features a two-piece design. Thanks to Castelli's advanced use of fabric technologies, the supportive foam core is slightly narrower and smaller than before. Flexibility and elasticity mean it sits exactly where it needs to be.

The upper layer of the seat pad is dimpled to reduce full skin contact, encouraging air to drive moisture away from the body. It's also more elastic so it doesn't fold while the finish is the softest ever on a pair of Castelli shorts. Vortex dimpled fabric on legs for aero performance.

Forza fabric on inner legs with 38% Lycra (R) content for the perfect fit. Stripe mesh engineered minimalist bib construction keeps you cool. Giro4 leg gripper elastic for better grip distributed over a larger area.

Doppio V construction in front for increased support and comfort. Flat-lock stitching. Progetto X2 Air Seamless seat pad.
