Castelli Sorpasso Pro Bib Tights Thanks to their robust construction and reliable performance in all conditions, the Castelli Sorpasso Pro Bib Tights offer consistent, pro-level protection so you can train through the worst of the winter months with complete confidence. Advanced Fabric Engineering and Anatomic Freedom At the absolute core of the Sorpasso Pro is Castelli?s specially engineered Definitivo warm fabric, which wraps the muscles to provide a premium blend of targeted warmth, supportive compression, and a flawless fit. To ensure your pedalling efficiency is never compromised, the tights feature advanced anatomic shaping at the hips and knees. This carefully sculpted patterning provides a natural bend that mimics your body's movement, guaranteeing a smooth, unrestrictive pedal stroke while keeping muscle fatigue at bay during long, freezing endurance sessions. Streamlined Details for Long-Distance Excellence Every element of this premium tight is optimised for zero distractions and long-distance comfort. The upper chassis utilises lie-flat elastic bib straps that stay perfectly stable without digging into your shoulders, while the lower leg is made with a zipperless ankle, significantly reducing bulk inside overshoes. Finished with a subtle embossed Castelli wordmark logo and sleek, modern reflective inserts positioned for maximum visibility from behind, these tights ensure you stay safe, fast, and ready for whatever the cold-weather season brings. Progetto X2 Air Seamless seat pad A pro-level seat pad engineered for maximum comfort. A plush, seamless skin-care layer feels super soft against your skin and reduces the risk of abrasion and irritation. A saddle-shaped cushioning layer features high-density foams and perforated gel inserts, giving progressive damping and support precisely where you need it most.
