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.

Good bib knickers are hard to find. These are very good with one exception that can be fixed. I have a pair of Castelli Rosso Corsa bib knickers from a few years ago and it seems the quality and details of construction of the older pair was better than these newer Sorpasso Rain Or Shine (ROS). I did find the leg grippers to be inadequate - the section below my knee would ride up to the point the fabric of the knickers would bunch up behind my knee. That doesn't happen with my older Rosso Corsa pair which have silicon leg grippers. I solved the problem with the ROS pair by buying silicon gripper material from Amazon (description below) and having those sewn in by my local seamstress. Now they're just fine.

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.
Works almost as expected. I have several other Castelli riding shorts, and with one exception I've bought size large. I'm 6' and 154 lbs. Large fits tight but and is not constricting. I decided to buy this bib short in XL and it fits comfortably. The only shortcoming is that the portion that covers my knees pulls up while riding and barely cover the top of my calf muscles. Otherwise it does a good job of protecting my knees from the cold.
This bibk-nicker replaces a previous Castelli Sorpasso knicker that simply wore out after 4 or 5 seasons. In a word this replacement knicker is terrific. The pricing was fair, the fit is tight (I'm a natural medium and one needs to move up one size for Castelli) so the large works well for me. This knicker is very comfortable from <45degrees to 60 degrees and feel quite nice on chilly southern California mornings. The pad is butt friendly on rides of up to 60 miles which is as far as I ridden with this knicker. I imagine they will suffice for extended mileage as well. Overall, a top-shelf knicker at a price that won't cause sticker shock or buyers remorse. Highly recommended.
I wear an XXL size in Castelli Men's Free Aero Race 4 Bibshort. I am 5ft 11in, 190 lbs.
I wanted to try some Castelli Bibknickers so I ordered initially a Castelli Men's Tutto Nano Bibknicker in the XXL size.
The Tutto Nano felt too heavy and thick compared with the Free Aero shorts. So I returned the Tutto Nano's and tried the Sorpasso RoS Bibknicker in a smaller size (XL). Mistake: They are extremely tight fitting (like the Free Aero Bibs). I thought that i would like the fit like the Free Areos, but the fit in the XL size is too tight to allow circulation in my legs. As a result, they do not provide warmth. This is primarily a sizing problem so I would just advise to buy the same size as your Free Aeros if you have a pair.
I'm 6'3" tall, 195 lbs, 32" waist and wear a 33" jean length. These bibs fit great! They do a good job keeping the chill off between 40 and 55 degrees. Also from 55 to 65 degrees in temp they are not too hot. Good fall spring riding choice piece of clothing.
