Warm, Water-Repellent Nano Flex Fabrics
The Sorpasso RoS uses Nano Flex 3G fabric, Castelli’s third-generation nanotechnology treatment that offers impressive water repellency without compromising breathability or stretch. It provides a supportive, lightly compressive fit that moves with you throughout long hours in the saddle.
Extra Protection Where It Matters
Panels of Nano Flex Xtra Dry fabric on the thighs and rear add wind resistance, warmth and protection from road spray, helping you stay comfortable when conditions turn cold or wet.
Engineered for Comfort and Fit
An anatomic cut at the hips and knees ensures the tights move naturally with your pedalling motion. The seamless bib straps lie flat and keep the tights and seat pad securely in place, reducing distractions on long rides.
Progetto X2 Air Seat Pad
Designed for endurance, the Progetto X2 Air pad uses a dual-layer structure to reduce friction and provide targeted cushioning. It delivers comfort and support for long hours on the bike.
Practical Details for Winter Riding
Reflective panels enhance visibility in low light, while YKK Camlock zippers at the ankles make the tights easy to put on and remove, even over bulky winter socks.
The Castelli Sorpasso RoS Bibtight is made for riders who want warmth, flexibility and reliable weather protection through the winter months. It’s a high-performance tight that keeps you comfortable, supported and focused on the ride ahead.
