Castelli Sorpasso RoS Bib Tights Women black/brilliant pink

The name of this tight, Sorpasso, means "overtaking" in Italian. That's what Castelli'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 Castelli's Nano Flex 3G fabric, the third generation of their 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.

Castelli then 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. Castelli's generously padded Progetto X² Air seamless seat pad make long rides more comfortable, and you have multiple reflective panels to keep you visible.

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

Nano Flex
Castelli take their thermal fleecy stretch Thermoflex fabric and coat it with millions of tiny nanofilaments to create the most water-repellent fabric finish ever. Drops of water stay as spherical balls on top of the fabric or bounce off the fabric without leaving a trace.

Progetto X² Air
The Progetto X² Air seat pad is used with its ventilated skin-care layer to keep you cool. Its two-layer design and multi-density padding ensures excellent comfort no matter how long your epic ride is.
