The height of apparel science.

We won't sugar coat it. For years, we've viewed Giordana's FormaRed Carbon bib shorts as the pinnacle of comfort. However, never being one to rest on its laurels, Giordana has finally surpassed the monolith of FRC, and the name is the EXO System Bib Shorts. Sure, a host of synonyms come to mind -- ambitious, advanced, etc. However, riding is believing, and in the meantime, you should consider EXO as a ground-up reinvention of competition cycling apparel. We're serious, it's that good.

So, you're surely asking, what is it that makes these bib shorts so phenomenal? Well, the name says it all. EXO is short for 'external optimization,' meaning that Giordana is targeting specific muscle groups and regions in order to enhance support and to reduce aerodynamic drag. Right, you've heard this before, but Giordana pursued this initiative with such vigor that it created four exclusive fabrics, and revolutionized the placement and construction of paneling.

Starting at the bulk of the construction, Giordana incorporated its certified Power Lycra fabric, Moovix, at specific leg panels that benefit from its compressive composition. In fact, with a composition weight of 210g/m2, Moovix's compression level is gravitating towards those found in recovery pieces. However, where it differs from these is that it does not feature the gradient design that propagates the enhanced blood flow to the heart. Instead, this material places a focus on muscle support and isolation. By doing this, the Moovix panels limit any needless muscle movement in the pedal stroke, while also protecting against the fatigue-inducing effects of road vibration and muscle oscillation. And while you might be thinking that this sounds overly tight and stuffy, Moovix actually features a hollow microfiber composition that's been knit into a honeycomb structure. Accordingly, the material retains an omnidirectional stretch, as well as breathing and managing moisture with ease.

These attributes are furthered, in a lighter degree, throughout the remaining leg panels. To achieve this, Giordana incorporated its new Granfondo material. This material features a higher thread count than Moovix, while also retaining a similar level of compressive-quality. Accordingly, Granfondo is lighter weight, softer, and more conforming to the muscle groups. In fact, it works almost opposite to the material that's been placed at the inner-thigh and seat panel, Zaffiro. Now, while Zaffiro is similarly soft at the inner-layer against the skin, this material's primary duty is to resist external abrasion, thus its placement at the highest points of friction. As a result, the life of the bib shorts is extended, and your legs remain free from any chafing.

Moving up the towards the waist, we find the same Ametista Core Contour system that's found in FormaRed Carbon. This system relies on the Ametista fabric, which is placed at the circumference of the waist. Again, we see a high-level, 200g/m2 Lycra, only now, Ametista is characterized by its woven-in carbon threads. With the carbon filament, material stretch is controlled, but not just in the supportive sense. Basically, the carbon reinforces the honeycomb-knit Lycra, making it lighter, yet stronger, and allowing it universally stretch in all directions, not just four ways. Additionally, the carbon fiber blocks out static and rogue atmospheric electrical interference for an increased anaerobic output and a delayed onset of fatigue.

At the rear upper panel of the hips, Giordana placed its new lightweight Illusion mesh panels in order to increase ventilation. This concept is furthered by the new AeroFix Pro uppers that provide both omnidirectional stretch and the utmost in breathability. And, of course, AeroFix Pro's primary duty is securing the precise, targeted fit of the EXO bib shorts. The flatlock seams of EXO have been oriented as to provide conformity to body within the cycling position. However, it also follows the muscle groups of the legs in order to provide the aforementioned isolation and support. You'll also notice that Giordana has extended this ideology by lengthening the shorts to just above the knee. Accordingly, EXO provides maximum coverage to the muscles. Altogether, the various components of EXO's construction create a second-skin fit that increases airflow over the body, reducing your aerodynamic profile.

The bib shorts' chamois is one that Giordana touts as being the most advanced in the industry -- the Cirro O.F.. We don't deal in absolutes, but we can say that it's the first chamois we've heard of with Aloe Vera particles directly infused into the threads of the microfiber. Aloe is not only a natural bacteria fighter, but its implementation in the fiber provides a cooling effect that protects and heals during activity. Below the skin layer, the Cirro has a 4mm-thick pad of waffled-texture expanding memory foam. The texture aids in ventilation by moving moisture to the perimeter of the chamois where accelerated evaporation can occur. The final layer of the chamois is a thick section of hand-sewn open cell padding with recessed channels for pressure relief. These technologies amount to a chamois that won't get wet and nasty 100 miles into a ride, let alone 20.

The Giordana EXO Bib Shorts are available in five sizes from Small to XX-Large and in the color Black.

  • Four fabrics including the exclusive Grandfondo
  • Cirro O.F. aloe-infused chamois with anti-bacterial properties
  • Form fit with anatomically placed panels and non-chafing bib straps
  • Flatlock seamed for comfort

why do good things cost so much

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

These are the best bibs I own. The legs don't slide up, the chamois is quite comfortable and they've got loads of compression.

The leg length is perfect for my femurs. They're not short shorts, which is nice.

One of my all-time favorite bib. While my other favs Assos tfi 13 and Castelli body paint 2.0 gave me a- stay with me- stretchy almost liquid huggie feel, the EXO gives a dry, yet excellent compressive feel. The pad has a nice supportive feel without the diaperness like Assos. And once on, I never think about the strap, because it never bunches or digs into my shoulders.

I've worn and washed this five times now and it looks brand spankin' new. I saw the seven washes and tattered look review. Like with any other high-end gears I quickly hand wash them soon after use.

Incredible fit for tall guys

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

I've tried several bibs throughout the years trying to find the perfect mix of extra length and comfort....look no further. I've tried them all, and this is BY FAR the best fitting bibs I've ever worn. I'm 6'6" 220 and these fit perfectly. I knew they fit small because a friend my size ordered them and warned me to add an extra size. Just rode 100 miles this weekend and felt like I could do another 20 without chaffing or discomfort. They are expensive, but worth every penny.

Great Fit for Taller Rider

  • Fit: Runs small
  • Size Bought: XXL

The fit, compression, and length of the leg make these a great purchase. I am 6'6", so, it is hard to find a bib that fits well. The fit through the torso and the leg length are exceptional. I can see how some people might find these bibs to be too long, but, not me. Also, the pad is very comfortable. Have used them 4 times in a two week period and really enjoy them.

Thanks for sharing your feedback on these bib shorts Joe!

Perfect fit & comfort

  • Fit: True to size
  • Size Bought: Large

These fit true to size, or at least true to the usual ranges given for bicycling clothing. I bought an L which is rated as 32-36 in and fits as good as any other bibs in that same range.
The chamois is as perfect as they come, the fabric is pleasant and I don't mind the slightly longer legs. Really the only complaint I have about these is that they stopped looking new after 5 or 6 rides. In other words, the EXO fabric seems to age faster even with delicate wash than other brands / other Giordana bib I own.

Great construction but odd length

  • Fit: True to size
  • Size Bought: Medium

These are well-made but if you are hoping to move up a model from the superb FR-C shorts, be aware that the EXO are inexplicably about 4cm longer than the FR-C so unless you have unusually long legs, they will hit you behind the knees. Same excellent shamois as the FR-C, and sizing is about halfway between Euro slim and USA.

giordana exo system bib shorts

  • Fit: True to size
  • Size Bought: xxl

very nice bibs they fit very well,very comfortable with lots of room


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

The 12 1/4 inch inseam is ideally suited for those of us with a long femur. If you check out the Giordana web site, you'll find that they are one of the few manufacturers that specify their bibs inseam length. The quality and fit meets the expectations of a higher end bib short.

Great offering from Giordana as usual

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: 2XL

Start with I own five pairs of FRC bibs. That said, the Exo bibs are very different, but perform very well. Make no mistake.........the multi-panel, multi-fabric concoction offers a LOT of compression. While my FRC's are tight, and form fitting, they feel like basketball shorts compared to these things. The compression is noticeable, and helpful when riding with tired or sore legs. They also have the Cirro Omni Form chamois which is by far my favorite. They do run a bit longer than the FRC's so keep an eye on your tan line. I think the increased length aids in the compression/aero thing. These bibs are tighter than you might be used to, but feel really good when in in the cycling position. For fit reference, I am 6'1" and weigh 185 or so. Big-ish legs with a 36 inch waist. Like all Giordana bibs, I wear a 2XL, so size up for sure.

I ordered the XXL based on your review and the sizing worked out well for me.

I'm 6'2.5", 255lbs. I've only worn these once on a weeknight 35mile ride and noticed an abrasion across the front of mr. pete. The front of the pad ends right at the base of mr. pete. Will give them one more try with adjustments.... ;-)

Great bibs

Giordana's EXO line is characterized by excellent materials and workmanship. I have used Giordana bibs for several years, and they are long wearing and comfortable. This pair is no exception. I'm not sure why they continue to increase in price, but buy them on sale and you won't be disappointed. These particular bibs seem to run a trifle large relative to G's historic Euro sizing. Would have been happier with an XL size, but they were all sold out.

Unanswered Question

does this fit similar to the vero bib?

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

So I just purchased the EXO bibs and the Assos s7 equipe and while I love the Assos bibs I used the EXO one time and sent them back to Competitive Cyclist, who were gracious enough to give me store credit. With the Assos bibs you forget they are there after you put them on and I found the EXO bibs to be very uncomfortable to me. In addition, the EXO bibs are very long and reached all the way to my knee cap. I will be ordering another pair of Assos but will pass on Giordana next time.

My Favorite Bibs Right Now.

  • Familiarity: I've put it through the wringer

From my closet of Assos FI.Mille S5s, Castelli Body Paint 2.0's, Capo Padrones, and Giordana FR-Cs, these are my favorite bibs right now.

The straps, and the compression at the thigh are just perfect for me, and I actually find the chamois more comfortable than that of the Assos, especially on long rides -- although it is close. As the description states, the legs are cut a little longer, but while I would prefer them to be a bit shorter, I don't mind them. The leg bands absolutely disappear -- even after many hours in the saddle. I've had no durability issues so far. What would I change? Not much...

Exo vs. Assos FI.Mille

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

My info:

Height 6'-3"; weight 195lbs; body type athletic.

I ride 3-4 times a week; regular rides in the 30-40 miles with one ride a week in the 70--100 miles.

I bought this bib for my long rides. Other shorts that I use for long rides are Assos fI.mille-s5. I bought the Exo in XL size and the Assos I use are XLG. I bought Assos XLG because that is the size that was recommended based on my height, although my next pair will be an XL, the XLG feels too loose on my waist.

I like the Exo better from the hip up. They are perfect on the waist and the suspenders are in my opinion superior to Assos, I really like the no-seem approach. Also I prefer the cut for both suspenders and on the front at waist level--a bit lower, more opened. I never felt the suspenders for the whole lengths of my rides. The chamois is good but Assos is better. For my liking Assos chamois is just perfect, everything, the fit, the padding. I have not found any other shorts that match that. Also, I like better Assos fit/fabric on the legs. The Exo after a couple of hours start feeling too tight for what I like and it bugged me.

I will use the Exo for my shorter rides and stick with Assos for my long rides, I will just try a size down on the fi.mille next time, to see if the waist gets a bit tighter but still maintains length on the suspenders. For the Exo, not sure if available, if I had a chance to purchase again, I would probably look into XXL to get more room in the legs.

    I just picked up a pair of these and I'm very impressed! I didn't think Giordana could do better than the FRC but they somehow managed. I have 5 rides on them now and its my go to short for anything from 50 to 90 degrees. The Compressions is noticeable and keeps the muscles happy on the longest of rides.

    I hate to say it, but my Assos shorts may now be set aside for trainer rides.

    Scary about the Assos comment. Love my Assos but thinking about giving them a go.

    Really glad to hear that yours are holding up. Bought a pair, did one long ride and the seams in the seat came apart. Sent them back and replaced them with the same bibs. The second ones did almost exactly the same thing. Sent them back for credit and have not replaced them . I have never had this happen with any of my other shorts. The shorts were comfortable but just did not hold up. I have not worn out another pair of shorts and to have these come apart after one ride was very disappointing, especially at the price. No problems with De Marchi, Gore or Pearl Izumi.

    Competitive Cyclist was great and credited both pairs as they promised. Can not blame them they totally stood behind the product.
