Cycling tights maximized to keep you comfortable — even on the coldest nights.

Improve your winter rides with tights best suited to take on a wide range of annoying weather conditions. Since Sorpasso means "overtaking" in Italian, manifest your ideals of the ultimate cold-weather ride with the Castelli Men's Sorpasso RoS Bibtight.

Constructed with top-of-the-line Nano Flex 3G fabric to make your rides a bit faster, better, more comfortable. This third generation of impressive nanotechnology fabric treatment adds a high level of water repellency without affecting the breathability, stretch, or warmth. A highly flexible, compressive fit will move with you, creating comfort that focuses on warmth without compromising with a lack of motion. The front panel and top of the thighs are created with Nano Flex Xtra Dry fabric to provide extra wind protection, as well as in the back of the legs to stay safe from road spray. Anatomical patterning secures a natural bend at the knee and the hip, while seamless bib straps lie flat keep everything secure. Featuring a generously padded Progetto X2 Air seamless seat pad to make long rides more comfortable.

Even when the weather gets cooler and darker, you can count on the Castelli Men's Sorpasso RoS Bibtight to make your ride just as comfortable as ever. Multiple reflectors provide visibility even on the winter solstice, and the compressive fit ensures maximum comfort even when putting in long hours through cold nights, keeping you warm, dry, and ready for tomorrow.

    Not as warm as I wanted

    These bibshorts have classic Castelli race fit, which means "not baggy." I'm 6' 2" 185 lbs and the XL size fits to a t. These are good down to about 45 degrees. But in colder temperatures, don't have sufficient heft to keep me warm.

    Works Great

    Castelli jackets and bib tights just work for me. These bib tights are extremelly warm and comfortable. With that being said I am 5'7" and weigh 150 lbs. So I wear a medium and they fit perfect. As all riders know, clothing is completely subjective, so take it for what it's worth. But I give these tights a big thumbs up.

    Great bib for California winters
    by Anonymous

    Holds up in 32 degree Fahrenheit weather up to 55 degrees. Light and easy to move in. It has been pretty durable and washes well.
