Castelli Sorpasso RoS Bibtight

The name of this tight, Sorpasso, means "overtaking" in Italian. That's what we've tried to do with this tight, to make it a bit faster, better, more comfortable. It's made to be technical equipment for riding in the widest range of winter conditions. The main part of the tight uses our Nano Flex 3G fabric, the third generation of our nanotechnology fabric treatment that adds a high level of water repellency without affecting the breathability, stretch or warmth of the fabric. You get a highly stretchy, compressive fit that moves with you, focusing on warmth and comfort.

But then we add a few panels of the Nano Flex Xtra Dry fabric to provide a bit more wind protection and warmth in the front panel and over the thighs, and in the back for extra protection from road spray.

It's not only about the fabrics: anatomical patterning gives a bend at the knee and the hip, while the seamless bib straps lie flat and securely keep everything in place. Our generously padded Progetto X2 Air seamless seat pad makes long rides more comfortable, and you have multiple reflective panels to keep you visible.

We've designed this as the go-to tight for a full winter's riding.
