Dangerously comfortable.

Occupying the pole position of a clothing line renowned for high-end materials and industry-leading innovation comes with certain responsibilities. Fit, function, style — every element of construction has to be as close to perfect as technology will allow. Giordana's FormaRed Bib Shorts and their Cirro Insert don't disappoint. In fact, we'd suggest that they should come with a disclaimer; after just a few miles in them, you risk developing a strong aversion to any other shorts.

The star of the shorts' construction is the HC-50 compressive Lycra on front and side panels, which replaces the previous model's HC-44 with an increased thread count — from 44 to 50 threads per centimeter squared — and a corresponding uptick in compression. With the added compression, these shorts are approaching medical grade, so they're more than capable of keeping your blood flowing and reducing the fatigue caused by road vibrations and muscle oscillation over long days in the saddle.

The inner thighs and seat panel feature another familiar name, with the Zaffiro material returning and upgraded to Zaffiro 2.0. It still features the same abrasion-resistant durability, but with an increased resistance to pedaling friction. As brand namesake Giordana herself cheerfully explains of HC-50 and Zaffiro 2.0, "Both are like their predecessors but better!"

The previous model's girdle of Ametista fabric returns unchanged, bringing 200g/m2 of gently supportive compression to your waist and core. It also incorporates carbon filaments, which reinforces the honeycomb-knit Lycra, allowing for a lighter build that retains the strength of a heavier material. The carbon implants impart antimicrobial properties, and Giordana claims that they also absorb atmospheric electrical interference for an increased anaerobic output and a delayed onset of fatigue. These shorts are comfortable enough that they've definitely become the long-distance favorites of at least one Competitive staffer, but we're not sure if that comfort is due to their exceptional construction, these claims of electrostatic interference, or both.

The shorts' body is kept in place by the usual bibs up top and the decidedly unusual 190 E leg bands down low. Given that we love them, we're compelled to highlight the latter. The 190 E bands spread a soft, non-restrictive, and gently compressive grip across the 7.5 centimeter-wide cuffs. A silicone application is used throughout these bands to help keep everything in place. The LoPro 0 used in the front and shoulders of the bibs is the distant, less-restrictive cousin to the LoPro 30 and 45 materials that Giordana uses in the cuffs and armbands of other items. The straps are hem-less for a perfectly flat fit that doesn't show through your jersey. At the shoulder blades, the LoPro is mated to 190 Mesh, which is soft and breathable with a barely-there feel that complements the band of ventilated Antigua material between the shorts' body and bibs.

The chamois is another returning star, the Cirro OmniForm (O.F.). It incorporates aloe vera particles for natural antimicrobial properties with a pleasant cooling side effect. The Cirro's 4mm-thick pad of waffled-texture expanding memory foam actively ushers moisture to the perimeter of the chamois to speed evaporation and limit bacteria-prone dampness. The final layer of the chamois is a thick section of hand-sewn open cell padding with recessed channels for pressure relief.

Clam diggers?

  • Familiarity: I've put it through the wringer

What is with Giordana? I used to love their bibs, but I'm 5'7.5", not 6'11". Their leg lengths are beyond ridiculous. The gripper material cuts across mid-knee, making for diaper rash at the back. I don't want to return to Eddy Merckx short-shorts, but this trend to cycling clam-diggers (capris) and goofy redneck Christmas-stocking socks (18" long) is both funny and pathetic.

Awesome Bib's

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

I have owned lot's of bike shorts with 30 years of riding and counting. Performance, Sugoi, Pearl Izumi, Assos and now Giordana. While I like my Assos NeoPro's, after my first 40 mile ride with the FormaRed, I am a FormaRed fan and I am already planning on buying another pair. I like them that much. They have great compression, the straps are not too tight and the banding around the legs fit snug and stay put. I know a lot of people said that the shorts run small, but no one person's physique is the same and I am not a 6 foot 180 pound rider, so these really work for me.

As I put more miles on them, I may update my review, but based on the build quality, fit and look, I am guessing I will not be...

5cm = 5cm shorter

    The size, "5cm" in the drop down menu is referring to the length of the short being 5cm shorter than their normal short length. Presumably for those with shorter femurs who don't want the bibs to go down to their knees. Hope this helps!

    I have a short femur (see my stats in the below review), yet these are much shorter than needed to keep the legs a couple of inches above my knees. Instead I'd say these are for those that want to channel the short-shorts of days gone by. They have the shortest inseam of any men's bikes shorts I've seen in atleast 10 years.

    Beautiful Design, But -5cm = Hot Pants!

    • Familiarity: I returned this product before using it
    • Fit: Runs small

    I love Giordana’s blend of technical features and quality construction, so I've wanted to own one of their bibs for several years now. However, their fit (both leg circumference and length) varies greatly between models. This has been a challenge for me as a small person (5’5”, 125lbs., 29”waist) with a leg length of a 5’2” person. Unfortunately the "hot pants" fit of these FR-C’s with a 5cm shorter leg length has led me to give up on Giordana for now. But first some background.

    BACKGROUND: In my search to find a Giordana bib that might fit without breaking the bank I previously tried on two other models in a sz. Small. First the Laser a couple of years ago, but this was too loose especially at the chamois area & at the leg bands which came down to the narrow part of my quad just above my knee caps. I then recently tried on the Fusion since the Giordana "inseam" chart shows that it's the shortest bib @ a 10” inseam (1” shorter than the Fusion) but it was even looser fitting than the Laser (larger than a sz. Medium Castelli) and, because of this, they fit as long & with even looser leg bands than the Fusion.

    Finally I decided to try the FR-C’s since they supposedly have a tighter fit than most other Giordana models. However, the feedback indicated that the supposed 11” inseam runs long which meant that they would once again end at my knee caps with leg bands flapping in the breeze. Competitive Cyclist recommended that I try the 5cm shorter (i.e., 2”) model which should've been close to perfect (that’s how much shorter the Laser & Fusion needed to be so that the leg bands could fit more snugly around a wider part of my lower quads).

    CONCLUSION: The FR-C’s are definitely a much tighter "race fit" than the Fusion or Laser...not quite as tight as Castelli Free Aero’s but close enough. However the leg length on the 5cm shorter model was 1-2” shorter than expected such that the leg bands ended well above my tan line and close to “hot pants” in look. I confirmed this surprise when I measured the inseam at 8” (not the expected 9”). Based on this they should be called "7.5cm shorter" - what gives? Otherwise these are beautifully designed bibs in every aspect (closer to perfect vs. the likes of Assos Equipe’s and Castelli Free Aero’s), but I am tired of returning Giordana bibs due to their fit suprises…so I’m raising the white flag.

    NOTE TO GIORDANA – Please make your fit more consistent between models. And why not make a race-fit bib (or a sz. XS one) with an inseam closer to that found on most other brands (i.e., 9”-10”) rather than giving me the choice between capri pant leg lengths (with leg bands that are too loose) and that of hot pants?

    What does the 5cm in some of the sizes represent?

    The inseam is 5cm (i.e., 2") shorter which should make the inseam ~9" (vs. the 11" for the standard FR-C). The Giordana website shows these shorter bibs as a separate item called "FR-C Bib Short 5cm Shorter". I just ordered a pair since I have short legs and this is probably the only Giordana bibs that won't come down to my knee caps.

    Still the best

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

    I finally had to replace the FRC shorts I bought in 2012, and was a little worried about replacing them with the new ones, based on earlier reviews. Fortunately, I went ahead. These seem to be every bit as good as the older ones. Still a great chamois and a great fit. And the straps really do lie flat. The comments about them being a bit tight are correct (but I have skinny legs, so it's fine). Yes, the marketing hype is a bit silly, but they really are great shorts,

    Just as described in the company product review, the FR-C Pro is a tremendous improvement from the standard FR-C bibs. The most noticeable improvements are the softness of the lycra and the omission of tightness and puckering in the cuffs.

    I always dreamed of a bib that combined the upper-body FR-C (straps and stomach support) and the lower-body of my Assos-Equipe.

    At last, my wish has been met. These bibs are my go-to bibs for my rides, typically, 3-hours in length. The FR-C Pro is definitely worth the cost, which by the way, is lower at this time than the regular FR-C!

    Bib Short Comparo

    • Size Bought: xl

    I bought these along with a pair of Craft and Castelli in a similar price range (they were slightly less) to do a comparison. The Giordana shorts are head and bibs above the others. The comfort and fit is unequaled. Well worth the extra money.

    good gear

    good compression, met all of my expectations

    The Best I've worn so far

    • Fit: Runs small
    • Size Bought: Large

    The size runs a bit small, I wear med in Assos and Voler and these fit like a second skin. I have 3 pair and they have become the go to long ride bibs, the fit is perfect, the straps very comfortable and theres enough stretch in front when relief time occurs!

    Overall Solid Bibs for the money

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

    Giordana did a great job on these bibs overall. Solid, comfortable construction, and overall high-quality. The chamois was a little big in the front for me personally, but may work better for others. I am 5'11" and a M fit very snug/race fit style. I liked them enough to buy another pair to match another Giordana jersey I had.

    Poor build quality

    • Familiarity: I've put it through the wringer

    As others have mentioned the build quality on these is extremely disappointing. After just a few washes the seam around the chamois has completely come apart in two different places and I see other seams on the legs that are looking ragged. I've seen much better durability with far cheaper bibs. Likely to be my last Giordana purchase.


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

    Excellent compression with padding in all the right places. Most weekends, I will do at least one ride of 65-80 miles or more. These are the bibs I usually wear since they perform so well on a longer ride. The top line Assos bibs may be slightly better, but cost more. So, these are a top choice. We will see how they wear over a long time, but for now these are showing no signs of wear or losing compression in the fabric. I am 61 years old, ride almost every day, I commute, ride road, [fast, 20+] and mountain bike whenever possible. So, I have tried a few different shorts over my 70,000+ miles of riding. These are at or near the top of that list.

    THE Best

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

    Understanding that what's perfect for one person isn't for the next, I'm simply registering my complete satisfaction with these bibs. The fit is perfect. The compression is perfect. The feel.... well if feeling like you've got nothing on is perfect, then it's perfect. For the biggest events of the year, these are my choice. Bravo!

    Poor quality control

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

    I own several pairs of the golden FRC 2013 bibs. I read the bad reviews from 2014-15 so I waited until now for an upgrade. Another disappointment from Giordana. All the negatives mentioned by another reviewer apply.

    The compression is way too much, making them feel much tighter. They are not the same size as previous FRC.

    In addition, the mesh on the back of the bibs is far less breathable than on my 2013s. The result is that they stay a lot wetter than they need to be.

    In my case, after using and washing them several times, the stitching started coming loose in 3 places. They are falling apart after ~10 uses. I expect far more from $250 bibs and I hope Giordana realizes they can't coast forever on the FRC brand with this kind of products.

    Excellent Quality 5cm

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

    I believe the compression factor of the bib, tends to make one think they run small. Therefore, don't size down, buy the size you normally go with. The compression on the thighs assist with fatigue. Where I'm not completely convinced, is not using chamois cream with these bibs. I still think it would be prudent to lather up some. Other than this, I think they're a great pair of bibs.

    Not so "improved".

    • Fit: Runs small
    • Size Bought: Large

    I love my 2013 and '15 FRC bib shorts. These are almost, but not quite the same, and for all the wrong reasons. True to the description they have more compression than previous models, bordering on too much. There is a seam around the top of the torso that just doesn't need to be there - the previous models didn't have it, and it started annoying me after 2 hours. Finally, the leg gripper material is less than ideal. This seems to be a trend. The '13 model had a great leg gripper, the '15 a little less, and now this. The shoulder straps are the same as before (awesome) but now they're sewn on to the bib instead of integral, and I have to wonder if this won't be a failure point down the road.
    Overall good workmanship, and great chamois, which is why it gets 3 stars. 2 stars deducted for messing around with a good endurance design and adding stitching for no decent reason.

    Perfect fit! Best Bib Shorts!

    Typically, I wear Castelli, but I thought I would give these Giordana a chance. I have ridden several 60 miles rides and the chamois is the best I have ever worn. No saddle numbness. The shorts run a tad long to my liking, but I really like the compression feel on my legs. I would highly recommend these bib shorts for long days in the saddle. I selected a medium bib short. I'm 5 feet 11 inch tall, 151 lbs, and waist is 32. True to size for me.

    Century Ride Performance

    Rode century ride in Rocky Mountains and hardly noticed I was wearing them. Large bibs and jersey were perfect fit. I wear Medium bibs in LG brand. Great fit and chamois comfort. I don't use any riding cream and never noticed any discomfort from the bibs. I also love my LG Equip bibs, but LG's designs of late are disappointing so decided to try something new. Glad I did!
