Castelli Sorpasso Bib Knickers -

Given the long hours that real base miles require, your winter gear ought to be at least as comfortable as the stuff you ride and race in during the peak of your season. The pad should remain comfortable over the course of a five-hour ride. The materials should feature little bulk while maintaining body heat so you don't feel like a first-grader bundled up for a winter's walk to school. The Castelli Sorpasso Bib Knickers are part of Castelli's Rosso Corsa line of products, and as a result they get the Italian manufacturer's very best treatment in materials, design, and fit.

The Sorpasso Bib Knickers begin with Castelli's top-of-the-line Progetto X2 pad, the same pad found in Castelli's best shorts. The top layer that contacts your skin is a made from a seamless, four-way stretch microdenier fabric designed to move in harmony with your body and eliminate the chafing that can come with materials with too little stretch. It receives an antibacterial treatment and is bonded to a variable thickness pad made from multiple density foams; the result is a smoothly contoured pad that places the firmest foam where support is most needed. Perforated inserts help to relieve pressure on the sit bones and perineum -- just where riders experience the greatest pressure.

The front of the knickers are cut from wind-blocking Thermoflex Core Due fabric. This two-layer material traps air in a hollow-core layer of polyester while moisture is transported to the outer nylon/Lycra layer where it can evaporate. A lighter material, Thermoflex, is used for the portions of the tights not exposed to the wind to offer excellent breathability. Giro++ grippers keep both the bib straps and calves in place. It's rare to find knickers that are this light and this warm.

Like the bibs in the Rosso Corsa line, the waist of the Sorpasso Bib Knickers is cut very low to eliminate restrictions on breathing caused by pressure on the belly.

The Castelli Sorpasso Bib knickers are Black/white and are available in six sizes from Small through XXX-Large.


  • Mid-calf length keeps your joints and muscles warm so you can get through your whole workout


  • Progetto X2 chamois keeps your nether regions comfortable on long rides


  • Hollow core fibers trap warm air and move moisture better than traditional fibers

Castelli Sorpasso Bib Knickers Reviews:

Positive Reviews:

Appearance and Fit: As with all Castelli items, you should probably size up if you have any quads at all. I have a 29" waist and took a medium--a perfect fit (see photo). The tights are smart-looking and tasteful. Even if you haven't graduated yet from the tricycle, you'll look like a pro wearing these.
Functionality: Knickers are for those days when its too cold for shorts but full tights would have you overheating. Castelli rates the Sorpasso knickers for rides in 54-68 degrees, but you can actually go much cooler. I've worn these on a 7am ride with clear skies and a 10mph wind when it was 40 degrees and felt perfectly comfortable the entire ride--dry and warm, but not hot. I can only see wearing these on the upper end of the temperature range if it was cloudy and windy out. The pad was like sitting on a cloud, it was that soft--I practically didn't even notice it. The Louis Garneau tights I have feel bulky and cumbersome compared to these--the Sorpassos are nearly as unobtrusive as Castelli's riding shorts. This is what you're paying for. With these knickers, you'll have gear that not only looks good but you hardly notice it's there.

I am 5'7", weigh 155, have a 31" waist. What size do I wear? Large. Even at that size my initial thought was that they were too small. However after a couple of wearings they have stretched out nicely and fit quite comfortably. I did experience, as some have mentioned, that popping sound like fabric tearing. However, a careful perusal of the garment shows no damage.
These are great looking knickers, very warm and comfortable, but you have to figure at least one size larger than you wear normally, even within the Castelli line. I own a pair of Castelli Ergo Knickers and Ergo Shorts, both in Medium, so there in no correlation between models and sizing. Get the right size and you will love them.

These are super-comfortable tights - just the right thickness and texture to be comfy in 40 - 60 degree weather. They keep out the wind, provide plenty of support, and the pad is just right - thick enough for long rides but supple enough to conform. My only beef (thus the four stars) is with the stick-on rubberized lettering. It started peeling off after just a few rides. It doesn't affect the utility, but you have to wonder why a company like Castelli would put its name in bold letters on a high-end garment and not make it look good.

I compared these to several other models of bib knickers available at RealCyclist. I am 6'1", 160lb. Size Large fits me just fine. Knee coverage is good, the grippers at the bottom are staying put but (unlike Pearl Izumi) not overly tight. Unlike LG bib knickers, that I happened to like otherwise, no bunching up at the knee region either. Straps are right on. Quality of he material/stitching is solid, though it looks like the lettering "Castelli" might come off soon indeed but I cannot care less.
Bottom line: try these

Only have a couple of miles on these knickers tonight, but so far I love them. Comfortable, nice pad and well designed. They feel great on your legs. Had to return my first pair for a larger size: I'm 6'0" and 188 and usually wear a 34 in jeans. Trying on the large I felt like I was tearing the stitching. The XL fit perfectly.

i got a pair of these last season and wore them a few times. They are very comfortable and do a great job in keeping the cold out. They do run a size small so i would suggest sizing up on them. over all a good pair of tights

These are great. I love the slightly thicker fleecy material used just over the knees, to keep your knees warm. Great for spring rides. They are really well made and light.

Keeps me warm and fits very well + the Flouro ones match the Gabba top colour - I may not be fast but I am co-ordinated :-)

Negative Reviews:

I have a lot of Castelli clothing. I ordered these in late November and didn't have a chance to use them until late December because it had been too warm. Anyway on the first ride I noticed faulty stitching at the top of the white flash on the left leg. On getting home and looking closer I see it is cause by the machinist not fully overlapping a seam join. I sent them back and got a replacement - exact model and size hoping it was a one off. On receiving the new pair they have the exact same fault in exactly the same place. Looking further at them, these have 2 other areas of faulty\incomplete stitching The red tape at the stomach is not stitched properly so it forms a hole and the Progetto X2 chamois is not stitched together properly. Needless to say these are also going back. This particular Castelli item is made in Morocco - must be poor quality control but very disconcerting.. As I said I have many other items of Castelli clothing and these have all been excellent. Not sure if I should risk a 3rd try?
