Castelli's Sorpasso ROS Bibtight, means overtaking in Italian. That's what they'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.
But then they 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. The generous padded Progetto X2 Air seamless seat pad make long rides more comfortable, with multiple reflective panels to keep you visible.
Made for long hours in the widest range of conditions, this tight features their ultra-stretchy, warm and water-repellent Nano Flex 3G fabric with the extra warmth of Nano Flex Xtra Dry on the hips and thighs, along with an anatomical cut and the Progetto X2 Air seamless seat pad for long-distance comfort.
