Do the work now, reap results when it counts.

Imagine being able to ride in cold weather with clothing that emulated all the best features of your summer-weight kit: bibs that didn't restrict breathing, a chamois as good as the one in your best shorts, and lightweight materials that didn't feel bulky or restrictive. The Castelli Sorpasso Bib Tights 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 Tights begin with Castelli's top-of-the-line Progetto X2 pad, the same pad found in their 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 tights are cut from Thermoflex Core Due to keep the wind out. 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 simpler fabric, Thermoflex, is used for the portions of the tights not exposed to the wind for greater breathability. Giro++ grippers keep both the bib straps and ankles in place. It's rare to find bibtights that are this light and this warm.

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

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

  • Hollow core fibers trap warm air and move moisture better than traditional fibers
  • Progetto X2 chamois keeps your nether regions comfortable on long rides
  • Ankle zippers make the early-morning dressing routine a little easier

Nice Tights!

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: XL

I'm a fan of Castelli gear, so I bought these to get me through early/late winter rides. I've used them down to about 40 degrees and they've been plenty warm enough, especially once you get moving. The Progetto pad is awesome. I'm used to Castelli shorts with the Kiss pad, and this is a nice step up. Some of the reviews mention the wind cutting through them, and I have noticed that a little bit. So I'll knock off a star for that.

Fit is typical Castelli - tight and racy. The XL fits the same as other XL Castelli shorts I have.

Fits like a glove.

I bought this pair as an alternative to a one-piece suit and it works great. The straps are a little bit thin in width, but the overall construction is holds together well.

As advertised...

Bought these for a spring/late winter tight. Castellis quality is always a draw for me. Tight fits great, love ankle zips. Chamois is great but as other people have written , very poor insulation for your junk. Want to love these at 5 stars but that's definitely a flaw. Have ridden in them down to 36 degrees here in New England...

Great cool weather bibs

    When it's 40F-50F and not windy, I'll reach for these. For anything colder than that, go for the Sorpassos with windblock on the front, or something else entirely. The wind coming through is noticeable until you work up enough heat. Even then, you can feel it on long fast descents.

    Excellent chamois and the cut overall is comfortable enough I forget they're there. Still not in love with the thin laser-cut shoulder straps which tend to roll even when you take the time to start them off flat and straight. I do wish the front were cut a little lower. That would create less pressure on your diaphragm, but it's not terrible. Plus, breaks would be a bit easier, too. The thin ankle cuff looks a bit delicate to me, but it seems to be holding up under repeated use. With it being thin it does fit comfortably into booties with no pressure points, though at these temps I'm usually just wearing toe warmers.

    Overall, they're some pretty good shorts especially when they're on sale.

    I live in these all year round

    • Familiarity: I've put it through the wringer
    • Fit: Runs small

    I cycling a lot (16,000+km last year) and I do long rides in all weather conditions. For me a long ride 20 hours plus.

    When you have to wear the same piece of kit for 20 hours plus, in temperatures ranging from below freezing at night and baking sun during the day, then these are my go to tights. Love them :)

    Good, but...

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: 3XL

    I like these tights, but they aren't perfect. 3 and 1/2 is the real rating.

    They aren't quite as warm as my Assos LL.HABUTIGHTS_S7 bib tights, which is fine - as it gives me a choice depending on the weather. 45-50 is a good range for these, below 45 and I reach for the Assos.

    The zipper around the ankle is a nice touch. The bib is a little high in front, but still workable for that mid-ride relief on long days (Assos is a bit better here).

    My one compliant is that there is a seam down the middle of the crotch that seems to want to shove the package to one side of the other. With a little adjustment the ride gets comfortable, but Assos definitely has a better fit in this area. Of course, the Assos is much more expensive, too - so that's a big trade-off.

    Like all Castelli, they run pretty small. I'm 6'3" and 205 and the 3XL works very well.

    Great tights!

    Solid pair of bib tights - keeps you warm and doesn't rub in any of the wrong places. Perfectly padded chamois. Great for rides in 40-50 deg F, maybe down to 35 deg if low wind.

    Great tights!

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: XL

    I love these bib tights. Same great chamois as my bib shorts, so no disappointment there, and I was already familiar with Castelli's rather small sizing, so my fit was fine. My winter rides in the desert start off pretty chilly in the low 40's and often warm up to high 50's. These are warm and toasty early on the ride, without getting too hot as both me and the temp warm up. Nice wind protection, again, without overdoing it and getting too warm. Front is pretty high, so pulling down for a "nature break" is quite a tug, but manageable, and the high front does block more wind. Overall, I'm as happy as I have been with all my Castelli bibs.

    Sizing question. Using Castelli's size chart, it appears that I should order a medium. But, several reviewers suggest sizing up. I'm 5'9", 148 lbs and 31" waist, 39" chest.

    Best Answer

    I'm 5' 9" and 175, wear an XL. It is a very tiny bit long (not bothersome at all) but otherwise I couldn't wear any smaller. I would think a L would be good for you.

    Thanks David. I had a suspicion that a medium might be too small for me. I'll go with the Large!

    Your size is "L"

    As other reviewers have posted---size up 1x if you're in the USA. Castelli runs small, so don't think you're buying fat pants. Cut the tag out and tell your friends they are a medium. 36-50 degrees are no problem. They block the wind like other thermal waterproof bibs I have that are 3x as thick and 3x more restrictive. The description is correct when it says its rare to find bibs this warm and light. I was simply amazed on today's ride in a 15mph wind that went from 45 to 36 degrees. They blocked the wind and kept me warm and I didn't overheat. There is a slight fleece lining that is super comfortable as well---the sit pad is top-of-the-line as other Castelli bib shorts I have. Castelli did very well on this product.

    Really love these tights

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I live in Minnesota so there is no shortage of cool to cold weather in which to ride. I typically ride from late March to early Decemember - basically from when there is no ice on the roads in the spring until the ground freezes for winter. When it freezes, I go to the fatbike with studs.

    I use these bibs in the temp range that they are specified by Castelli (see their website) and find them to be accurate during daylight. The best part of these tights is that they really work for a very, very wide temperature range - more than any other tights I have ever owned. They wick and breathe well but they are also pretty wind proof.

    A couple of weekends ago, I used them for an all day ride that went from 28F to 46F all in the same day. Amazingly enough, at no time was I cold, at no time was I damp from sweating and at no time was I too hot. That is an incredible accomplishment for a winter/cool weather piece of cycling clothing.

    I would prefer that the straps, front/back were more consistent with Casetelli's other bibs and tights but it's not really a big issue. The reason they do it the way they do is to let you control the layering instead of forcing a layer on you. That works for me as well.

    Very happy with these tights.

    OK, but not as warm as Castelli says

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    Fit is very good, but you have to accept these are performance tights with substantial compression, you're not going to able to just throw them on. Take your time, and wear them around the house a bit when you first get them and they'll loosen up and conform to your body. Size is dictated waist measurement, not how tall you are, how much you weigh, what size you take in Pearl Izumi, Louis Garneau, Assos etc, it doesn't matter. Just use the Castelli chart for a perfect fit.

    The ProgettoX2 pad is great, so that's a good reason to get them by itself. However, these don't keep me warm down to Castelli's rated 32 degrees. They make riding at that temperature possible, but I feel the cold more than I like. Their comfortable temperature range seems like high 30s to mid 50s, at the most. If you're OK with the Kiss3 pad get the Ergos, or any other Castelli tight with Thermoflex, temperature range is the same, although these do have a bit more compression and "vanish" more than the Ergos. I like the ProgettoX2 better so these are worth it to me for rides over 2 1/2 hours, shorter than that and the Ergo/Kiss3 works almost as well.

    Update 2/2016: after using these now for 1.5 winter seasons I can say these are definitely not warm enough for mid/hi 30s and down. And they barely work from 36/37 to low 40s. Their main problem is they let wind right through, no wind blocking at all. Best temps are really about 42/43 to mid 50s. Still nice tights when used within their capabilities. The Ergos I mentioned above are a bit warmer and block wind better, but with the caveats as noted.

    Update 12/2016: 1) These are wearing very well. No loose threads, seam separation, holes, decal delamination, etc. Still basically like new into their 3rd year of use. 2) It's probably me, but I'm going to adjust my estimate of their lower comfort limit up to mid 40s, and even higher if it's very windy and no sun. They are just not true winter tights, rather early spring and late fall. Their two virtues continue to be the excellent pad and low constriction for a full tight.

    Great at first, then downhill

    • Familiarity: I've put it through the wringer

    These bibs indeed keep me at a "normal" riding warmth on colder days. Do I still feel the nip when the temperatures start to drop or after 4+ hours on the bike? Yes, because the sweat in the fabric is amplifying the colder wind. Overall, these were and have been great at least for warmth without going to the "thermal" option. NOW the downside, you need to slowly, and carefully put these on. Like a wetsuit, little by little or else you will hear the preverbal tear sound of the stitching. I usually wear a small to medium in bib shorts and with these a LG is just enough. The most disappointing part of these bib tights came today before my ride. I wanted to really look these over again before I wrote my review, and definitely have logged many miles in them. The outside material where the chamois meets the saddle is all pillowed up and has a "chafed" look to it. I was pissed to say the least. I wash these as directed, always hang dry and about 300 miles and 4 weeks later this is happening?? Sorry Castelli but I am very disappointed in the cost to what is going on at the contact point. My saddle is a leather San Marcos with no grippy materials, etc. to cause such material breakdown. I am actually considering returning these for a different pair due to the disappointment in what I think is the most important part, and the only contact part with the bike. Castelli has a warranty supposedly, and I have yet to return anything from Competitive Cyclist either due to their existing great products but guys, for this money, this is not something that should happen to high end bib tights. Due to the lack of construction quality, I gave this a 2 star. If the materials had held up, you would have seen 4 stars. Competitive Cyclist, what can be done with this?

    Bib Tights that work well

    • Familiarity: I've put it through the wringer

    I've purchased Castelli Bib Tights of all types, From the super-warm polars to the new Sorpasso's (standard and wind proof models). They are always tight, or 'race fit', but are comfortable on the bike, and always keep me warm, sometimes too warm.

    I live at 7000 feet, ride at over 8000 at times, with bitter cold winds, during the off season, windchill anywhere from 5 to minus 10 Fahrenheit. These bibs work.

    Excellent all around

    • Familiarity: I've used it several times

    I've never owned a pair of winter-specific bibs and decided to finally get some. I couldn't be happier with this purchase. For starters, I'm just shy of 6'2", 165 lbs, and the Large fits me perfectly. Couldn't ask for a better fit. Castelli stuff does fit a little smaller than most brands. I have a Castelli kit in size medium and went with a large in these bibs based on a recommendation from someone similar to my size, and I'm glad I did.



    The first time I wore these, it was 47°F, calm, and misting on and off. My second ride was 50°F, sunny, and fairly windy. In both conditions, I was incredibly comfortable. I feel like these bibs would keep me warm down into the upper 30s, and I consider myself more sensitive to the cold than most. My legs were a bit chilly for the first 15 minutes or so, but that's what you want. If you start off warm, you'll just get hot. Within a half hour, I felt absolutely nothing, which is exactly what you want in cycling clothing. The less you think about it, the more comfortable you are, and these bibs helped me feel more comfortable in cold weather than I ever have before.



    They're insulated enough to keep you warm but breathe well enough to keep you from feeling sweaty. The inner material is incredibly soft, and as many others have said, the chamois is definitely top of the line. Some others have commented on hearing a ripping noise when stretching the seams. I've heard this too, and I've heard it in other Castelli products I own. I assume it's some kind of inner stitching because I've never actually seen rips or tears anywhere on the seams to indicate where the sound is coming from, so it's nothing to worry about. I lucked out and got these on a Black Friday sale for $98. I will be buying another pair when I see them around that price again.

    Way Too Small!!

    • Familiarity: I returned this product before using it

    Very disappointing. I'm 5'11" and 190lbs. I ordered the XXL which appeared a little large based on the size chart. Other reviews said to go up a size, so XXL looked right. Not only were they 3" too small around the waist, they were at least 3" too short in height. I returned them and will probably go with some Louis Garneau tights. Have never had much luck with Castelli clothing.
