Wearing leg warmers for cold weather rides is so passé when you have tights as warm and comfortable as the De Marchi PRO Bib Tights — one layer of thermal fabric and you're out the door.

De Marchi's PRO Bib Tights were constructed from the patented Roubaix fabric. Developed for cold weather riding, Roubaix is a winter-weight microfiber that uses an interlocking knit construction. With a fit and external feel similar to standard Lycra, Roubaix provides a thicker knit and a warm, fleecy feel against the skin. Additionally, the fleeced interior holds body heat against your skin while it also wicks moisture away. After all, it's no fun to ride when you're soaked with sweat.

Now, you might not have known this, but CyTech is actually the brainchild of De Marchi. So, to say that De Marchi knows a thing or two about a chamois is gross understatement. Applying this knowledge, De Marchi outfitted the PRO tights with an Elastic Interface Technology Race insert. This chamois uses a variable density throughout the pad to support the regions that need the most support, without impacting the ones that don't. And for CyTech, the support focus is primarily placed at the perineal, ischial, and gluteal areas -- the points most prone to distress from saddle pressure and compression. With its anatomic, Elastic Interface design, the CyTech chamois creates an abrasion-free support that promotes an increased circulation by protecting nerves like the pudendal. Even more impressive, the CyTech chamois is road-specific. CyTech engineers realize that saddles and saddle positions vary throughout different disciplines of cycling, and the PRO's chamois density patterns are mindful of the specific pressures of road cycling.

The De Marchi PRO Bib Tights are available in five sizes from Small to XX-Large in the color Black.

Here's what others have to say...



  • Familiarity:I've used it once or twice and have initial impressions

I believe I'm spoiled by my Assos shorts! These De Marchi tights have a mediocre pad, with no anatomical considerations for your most sensitive areas. I spent most of the last 100 mile ride I did in these tights readjusting my junk... And yes, like the other reviews said, I have no idea why the opening is so large at the ankles. Are Italians particularly fat ankled? It's bizzare! May return them.


I was so happy I bought a second pair

  • Familiarity:I've used it several times

I followed the sizing chart and the bibs fit great! (6'4 205 lbs size XL). I have done several century rides with these bibs and have been very pleased. They are warm enough to keep you comfortable out in the wind, yet they still breathe well and do not feel clammy. The shammy is comfortable enough for 5+ hr rides. For the price, they have exceeded my expectations.


A teeny big in the legs but meh.

  • Gender:Male
  • Familiarity:I've put it through the wringer

Bought these on sale. Wore them out on various bike rides (20-40 degree winter weather) and decided either embrocation cream or thermal tights were needed. As the title suggests, they are a tiny bit roomy through out the thigh but all in all they are well worth the money. The chamois is very comfortable.

Is that a beer in your hand? Strong work


Runs true to US sizes

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:True to size

I purchased previously a short bib from the same DeMarchi Pro family and was surprised to find this tights run more like the US size rather than the European cut. I am 6 feet, 185 lbs. and bought the Large size and fit perfectly. It's just an inch or less long at the bottom, but you can't tell when you are riding. The short bib version was so small that I had to buy XXL instead. Anyhow, I have used it twice in 50-60 mile rides (road) in FL at 40 degrees F and it provides the right amount of protection without overheating. They provide good compression and have not felt hot in the back at all. The chamois feels good for such mileage. Overall, I think they are great for the price and the quality is right on...they are a keeper!

Stated sizes apparently run large

  • Gender:Male
  • Familiarity:I've used it once or twice and have initial impressions

OK, reading through the negative reviews about this had me concerned. But a common thread (unintentional pun) was that the tights seemed to be too large and ill-fitting. So, I ordered the next size down (I'm 6', 154+/- #'s). Initial impression? They fit quite well on me -- even around my non-sprinter thighs. Yes, they are a little loose around the bottom leggings (calves' area was OK), but it's to be expected without zippers. In my view, that's a plus, as I don't get the binding around the ankles, which decreases the blood flow trying to keep you warm. I was pleasantly surprised with the fabric weight/thickness. Suitably insulated, not too puffy, and moved well with me on the bike. I tested these on my 20-minute AM commute in upper-20s degree (F) weather, and they performed as needed. I'd suggest a petroleum jelly or other embrocation for the knees for extended cold-weather riding as insurance, however.


Unbelieveable Bib

  • Familiarity:I've used it once or twice and have initial impressions

Bought this Bib last week and it is the best bang for the buck. Matched up to my Castelli, Canari, and Pearl, this Bib was beyond what was expected. Based on all the negative write-up, I almost did not buy. But this is why you take others' comments with a grain of salt. This is a magnificent piece and it is well worth the price. I did a 50 mile ride and my legs was warm and felt good right through. This is definitely a keeper and matched up with the very best out there.


Sizing is NOT typical Italian

  • Familiarity:I returned this product before using it

I don't know what's up with DeMarchi, but the sizes are NOT typical of Italian clothing. I'm an XL in Santini, Nalini, etc. but I'll need to swap the XL's I ordered for M's! Otherwise they look great, as expected from Made in Italy stuff.

I own a lot of De Marchi clothing (and Castelli and Santini). When you purchase De Marchi you receive classic styling, high quality CyTech chamois (esp in the higher end pieces), high quality fabrics and perfect QC, always Made in Italy (including the fabrics), and family owned since 1947. That said, sizing is a challenge with Italian brands. All Italian brands. Sizing can be specific to each individual item. Yes, it is a PITA.

I'm usually a XL in Castelli jerseys, a XXL in Santini jerseys, and usually a XL in De Marchi jerseys. BUT I'm a L in these specific De Marchi long-bibs. Go figure. The charts are often misleading. That's why these forums exist.



  • Familiarity:I returned this product before using it

Bought on sale, the right size per the size chart (L), but found them way too long for my size & height (just over 6', 165lbs), a bit loose, and the fabric lighter/thinner than expected. Returned them- appreciate the fast credit from CC. Will look at other brands.

  • Familiarity:I've used it several times

I used the fit guide included with the description of this tight and find them to be too large for me. At 5'6" the guide suggests a medium. The medium is loose and long! Small would have been the better choice. That said, the tight are very comfortable and the chamois is fairly comfortable for several hour rides. The tights are relatively warm, comfortable on rides that have dipped into the 20's.

No Compression

  • Gender:Male
  • Familiarity:I've used it several times

I own a few pieces of De Marchi and everything fits me perfectly in size M except this tight. The cut does not contour with the body and the fabric has no compression, so that leaves the fabric bunching up here and there and the rear looks like wearing a wet diaper. No zippers at the ankles and the elastic grip bands are kind of too big. They use the same material on the upper back panel which I think is not very breathable, overkill and overheating in the back easily. A friend ordered this for me at 50% off and I didn't want to bother him to return it, so I just gave it away to a college kid in my cycling club.


Weird Sizing

  • Familiarity:I returned this product before using it

Does not fit right. I am six feet one inches, 180lbs, bought an X-large and the legs are very baggy. In fact, the bottoms by my ankles are very loose and not even tight against my skin. Zero compression. They also are lined with fleece all the way up to the lower part of your neck and for me I like to have a better moisture wicking meshy material in the strap in back. Will be returning


Perfect Fit!

    This is just to comment on the fit, which is perfect for me. I'm 5' 5", 29" waist, 125 lbs. so fairly slim and I got the Small size. I have yet to try it on a cold day, but my initial impression is it's well made and the material seems to be of very decent quality. Looks warm but we'll see. Right now I'm just glad I got the right size!
