Castelli Sorpasso Bibknicker

Proudly bearing the esteemed Rosso Corsa logo, the Sorpasso bibknicker oozes Italian quality. Every technology available to Castelli has been put into this garment and the result is that it's lighter and warmer. So, when the temperature drops, you can keep riding your bike to stay fit over winter.

The Sorpasso bibknicker features Thermoflex Core Due fabric. This fleecy fabric is extremely soft to the touch and traps a layer of warm air next to your skin. With a tighter knit than standard Thermoflex, cold air is kept out. Should you begin to overheat, a push-pull moisture management system will keep you dry. Giro++ seamless bib straps sit flush against the body, for exceptional comfort.

To ensure complete comfort on long rides, the Sorpasso bibknicker features Castelli's Progetto X2 Air seatpad. The Progetto X2 is produced using 3 layers, each of which has a very specific purpose. To provide comfort where it's needed most, there is perforated viscous padding at any high pressure areas. Multi-density foam is used to provide variable thickness - padding where it's needed and less where it isn't, to maximise your freedom of movement on and off the bike. Finally, a four way stretch, antibacterial layer allows air to flow into the surface fabric to aid evaporation. Castelli calls this "the most comfortable seat pad on the planet" and we don't disagree!

As a cyclist, your power comes from your legs and much of this comes from your knees. That's why it's important to keep them warm! The Sorpasso knicker gives 3/4 length coverage, with silicone bands at the knees to keep them in place.

When getting those extra training miles in means venturing out in the dark, reflective Castelli logos will help keep you safe by making you more visible to other road users.

All in all, the Sorpasso bibknicker is one of the most advanced garments out there. Putting in those long winter miles will be a pleasure!

With roots dating back to 1876, Castelli has been at the forefront of fabric technology for almost 40 years. Alfredo Binda, Gino Bartali, Fausto Coppi, Jacques Anquetil and Louison Bobet were but a few of the legendary athletes clothed by Castelli. More recently, Bernard Hinault wore the first windproof jersey when he won Fleche Wallone. Castelli made that too!
