Proudly bearing the prestigious Rosso Corsa logo, the Sorpasso Wind bibtight oozes Italian quality. Every technology available to Castelli has been put into this garment and the result is a lighter and warmer tight. So, when the temperature drops, you can continue to ride your bike and stay fit By adding their thick, fleecy Windstopper X-Fast 2 fabric to the knee and thigh area, Castelli has made the Sorpasso Wind bibtight perfect for areas that are just too cold for the regular Sorpasso. For the remainder of the Sorpasso Wind, Castelli has kept the same, highly effective fabric as the Sorpasso - Thermoflex Core Due. 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 Wind bibtight 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!The Sorpasso Wind bibtight features an ankle zip, which allows a snug, yet comfortable fit. This snug fit keeps cold air out and allows the hollow-core fibres to trap warm air next to your skin. When getting those extra training miles in means venturing out in the dark, reflective tape around the zip will help keep you safe by making you more visible to other road users All in all, the Sorpasso Wind bibtight is one of the most advanced garments out there. Putting in those long, cold winter miles will be a pleasure!Features: Quality Italian design and manufacture Thermoflex Core Due fabric provides excellent warmth and breathability Windstopper X-Fast 2 thigh and knee protection for cold weather riding State-of-the-art seat pad for complete comfort on long rides Ankle zips with reflective tape allow you to be more visible to other road users Temperature range: -4°C up to 8°C Fabric: Polyamide, Polyester, Elastane Weight: 308g (size S)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!
