Take the chill out of your winter with the Castelli Men's Sorpasso RoS Bibknicker.
The name of this tight, Sorpasso, means "overtaking" in Italian. That's what Castelli envisioned with the Castelli Men's Sorpasso RoS Bibknicker — to make it a bit faster, better, more comfortable. Made to be technical equipment, making a ride in the widest range of winter conditions possible for a cyclist with any amount of experience on the bike.
The main part of the tight is constructed with Nano Flex 3G fabric, the third generation of impressive 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 flexible, compressive fit that moves with you, focusing on warmth and comfort without making any compromises. To spice things up, a few panels of the Nano Flex Xtra Dry fabric were added to provide extra wind protection in the front panel and over the thighs, as well as in the back for extra protection from road spray. But 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. Featuring a generously padded Progetto X2 Air seamless seat pad to make long rides more comfortable.
With multiple reflective panels to keep you visible, ride more confidently than ever in the Castelli Men's Sorpasso RoS Bibknicker. As the go-to tight for a full winter's riding, never suffer though long hours through cold nights ever again.

Excellent Knicker, let down by the pad.
I'm a huge fan of knickers. I have owned several pair from several different companies. When my go-to pair for 40-50 degrees, finally wore out, I was on the hunt for a new pair.
I was looking at these and the Giordana FR-C Pro and was told by CS that the Castelli should be warmer. I bought both and while I loved the fit and pad of the Giordana, I could tell they were not going to be as warm.
I'm 5'9" and 160lbs and got a Medium.
The fit is very good. The length goes to just below my calf, which is what a proper knicker should do. They are warm and windproof in the right areas. I rode these on a really foggy day and I was getting moisture build up on the outside of the legs, but stayed dry. The straps are excellent. The fabrics are excellent quality. I never felt clammy.
The bummer is the pad. While Castelli calls it their top of the line, I prefer the KISS AIR 2 pad. The Progetto X2 pad in these, is not as comfortable. It kinda just flattens out and you feel your seat more. It also feels a little forward and I have to pull the tights from the back occasionally. I know Castelli designs some of their clothing to be race fit and thus worn in a more aggressive, bent over position, so maybe that's what's going on here.
I have the Nano Tutto Nano kinckers and while they are not as warm, the KISS AIR 2 pad is much more comfortable.
Over all these are a great knicker for Mid-weight warmth. Fit great, but the pad keeps these from being excellent for me.
