The Castelli Free Aero RC Shorts, which are engineered for racing and made with dyed fabrics for a rich colour, expertly combine luxury with speed, being built around Castelli's best seat pad, the Progetto X² Air seamless.

Constructed with two densities of foam and gel pads, to absorb vibrations and improve ride quality, not to mention a soft upper layer that moves with the skin, this pad offers superb long-distance comfort.

Another top feature of these shorts, which are made from super-light, stretchy Forza 2 fabric that simultaneous supports and compresses the muscles, is a dramatically reduced number of panels, for less seams and added ease of wear.

Meanwhile, after 28 prototypes and their most extensive testing programme ever, Castelli has succeeded in creating a raw cut leg ending that stays put without grippers - their most comfortable ever.

Also sporting a supple raw cut waist and reflective piping down the back of the legs, the Free Aero RC Shorts expertly pair top-class performance with supreme comfort, making them some of the best that Castelli has to offer.

Key features:

• Constructed from dyed Forza 2 fabric with 32% Lycra
