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.

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.

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

  • 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

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

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: Large

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!

The BEST I ever had!!

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

After 36 years in the saddle with such names like Pearl Izumi, Louis G and Castelli, I felt I owed it to myself with the Best: Giordana Forma Red Carbon and an Assos Equip. The perfect blend would be the ‘Red’ from the waist up, with the Assos from the waist down. No complaints, though. The straps totally disappear as they hug my base layer in place. Because I am not physically challenged, unlike the Assos, my bibs don’t dip below my belly button when I need a nature break.
In closing, I would highly recommend both these makes (same price, too!) if you plan days of 3+ hours in the saddle.

The FormaRed is Back!

  • Familiarity: I've put it through the wringer

I've been a fan of the FormaRed Bibs for years. That is, until last year. Giordana really dropped the ball on the 2014 line when they dumbed-down the materials (no doubt to promote the Exo line). Really disappointing.

Out of previous loyalty, I thought I'd give the 2015 line a chance. I'm glad I did. Giordana appears to have learned their lesson. The materials are sturdy and high quality. The compression claims are legit. These shorts have the most compression of any FormaRed model that I have tried. The shoulder straps are a significant improvement over the previous year's model (although still not as good as 2013) and I don't notice them while riding. As always, the insert is top notch.

These are my go-to shorts for longer rides. The fit is standard Giordana. Yes, they feel slightly tighter than previous models but that is what compression is all about! I recently purchased several more pairs during the latest sale - just in case.

A Little Tight

  • Familiarity: I've used it several times

I read Rogerio's review about size, but since my previous Giordana medium bibs fit great I stayed with medium. Giordana said they intended more compression...I'd say a lot more. These mediums are definitely on the limit of OK for me. Maybe a 1/4 size too small compared to previous versions, but absolutely livable.
That said, their beautiful! The quality matches expectations, I can't wait to give them a roll.

Completely wrong size!

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

It is not my first Giordana piece. I have one of FormaRed knickers and they are great. At this time I bought the bib version of the same model.
When I received it I realized they run extremely small. The large size fitted perfectly for my 12 years old skinny boy...very disappointed!
It will be returned.
