The Sorpasso tight is Castelli’s go-to performance tight for the cyclist who rides seriously throughout the winter months. The Sorpasso RoS Wind Bibtight takes the standard Sorpasso Bibtight but adapts it for the most extreme cold weather riding.

This version adds GORE-TEX® INIFINIUM™ fleece-backed panels to the upper front of the tight as well as the thigh area to prevent windchill and keep muscles at an ideal temperature. Many wind tights sacrifice fit, comfort, or breathability for wind protection, but the two-way stretch of this fabric combined with careful patterning makes for minimal compromise and maximum comfort.

The non-windproof sections of the tight are made from Castelli’s Nano Flex 3G and Nano Flex Xtra Dry fabric to provide mild compression, softness, stretch, and the third generation of Castelli’s proprietary water-repellent finish.

The Bibtight uses Castelli’s Progetto X2 seat pad. This pad features two isolated layers that work in tandem with your body and saddle to eliminate friction while still offering substantial cushioning where it’s needed most.

No detail is spared with the Sorpassso RoS Wind Bibtight. An anatomical cut to the hips and knees increase comfort. Lie flat bibstraps make for a hassle free fit on the upper body while holding everything in place. YKK® Camlock® zippers at the ankle make for secure closing. Large reflective panels on the ankles provide moving reflectivity, for the low light conditions you’ll probably find yourself riding in while wearing these tights.

This is the tight for you if the cold isn’t something that stops you from riding, ever.

Men's and unisex Castelli sizing is based on your physical measurements and the garment's intended use. Race items are designed to use fabric stretch to achieve a very snug fit; as such physical garment sizes vary within the range. Please don't compare sizing with other manufactures. The sizes shown above are for the maximum size, so someone with a 99cm chest would be a size L. If you have a 101cm chest then you're an XL.
