We know what you're thinking, a long sleeve jersey for summer racing? Well, we'll let Giordana respond to your inquiry with a resounding 'yes.' Already being hailed as the next generation of cycling jerseys, the new EXO System Long Sleeve Jersey represents the pinnacle of compressive, cooling, and comfortable jersey design. Essentially, it's the jersey of the future.

It's no secret that Giordana recommends wearing the EXO system as a 'system,' meaning that the jersey and shorts are intended to function as singular entity. However, while the EXO bottoms place a focus on compression, the jersey draws its inspiration from aerodynamics. The reasons for this are simple. While the benefits of compression design are easy to follow at the legs, your legs don't have lungs to worry about compressing. This imposition on breathing left Giordana to focus on aerodynamics at the torso and compression at the sleeves. Why the sleeves? Because the arms are the upper body's first response to road vibration and the resulting muscle oscillation. Accordingly, the EXO jersey features Giordana's newest fabric, Asteria 2.0, at the upper-sleeves, shoulders, and center back panel, and its Moovix material from the elbow to the wrist.

Now, Asteria 2.0 isn't a 'compression' fabric. Instead, it features a relatively high composition weight of 130g/m2. However, where it lacks in fiber weight, it makes up for in threads per square centimeter, or TPC. Prior to this material, Giordana's HC44 fabric boasted the highest TPC in the cycling industry, at 44TPC. However, this high thread count is now shared with Asteria 2.0. Accordingly, the characteristics of this construction lend themselves to increasing the softness of the material, while concurrently improving the fabric's ability to conform to the body and manage moisture. So, with this balance of strength and conformity, the arms' muscle groups are thoroughly supported, while still retaining their ability for movement and flexibility.

From the elbow down, Giordana incorporated its certified Power Lycra fabric, Moovix. 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, 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.

At the front panel of the EXO jersey, we find another new fabric, A.i. One. This material is exclusive to Giordana, and you're about to find out why. A.i. One was commissioned by Giordana, making proprietary alterations to an already stellar construction. The end result is a two layer fabric that's composed of two different filaments. At the inner-layer, Giordana implemented a 'special' weave that essentially creates air pockets between the skin and the material. Of course, this creates a cooling sensation, but the weave also enhances breathability, while rapidly wicking moisture away from the skin. At the outer-layer of A.i. One, Giordana incorporated a polyester microfiber that's produced from recycled materials. And like the inner-layer, the outer-layer also makes use of a 'special' weave. Accordingly, this layer features an omnidirectional stretch that Giordana describes as 'mechanical stretch.' Additionally, Giordana added two separate treatments to A.i. One, an antimicrobial and an adaptive. So, one prevents the proliferation of bacteria in the fabric, while the other aids in thermo-regulation. As a result, you remain clean, comfortable, and more importantly, cool.

Along the rear panel, Giordana borrowed technology from FormaRed Carbon, incorporating its Host Carbon fabric throughout. This material features a lightweight composition with a carbon fiber filament. Why? Essentially, with the carbon filament, material stretch becomes omnidirectional and controlled, but not just in the supportive sense. Basically, the carbon reinforces the honeycomb-knit Lycra, making it lighter, yet stronger, and allowing to universally stretch in all directions, not just four-way. Additionally, the carbon fiber blocks out static and rogue atmospheric electrical interference for an increased anaerobic output and a delayed onset of fatigue.

Now, the omnidirectional stretch of the aforementioned fabrics allow the jersey to sit closely next to the skin without inhibiting your freedom of movement. And as a result of this 'next-to-skin' fit, airflow remains more attached over the body, minimizing your aerodynamic profile. Not surprisingly, Giordana incorporated a few more features in order to bolster this design trait. At the collar, Giordana utilized what it calls a 'no-profile integrated collar.' This means that there's no material over the neck, streamlining your body position whether over the hoods or down in the drops. Additionally, the sleeve position is secured by Giordana's venerable LoPro 30 cuffs. These are comprised of a very low-profile band with an internal silicone gripper for attachment.

For storage of ride essentials, the EXO jersey features three rear pockets that have been given flaps in order to maintain the jersey's aerodynamic profile.

The Giordana EXO System Jersey is available in six sizes from Small to XXX-Large and in the colors Black/titanium and White/black.

  • A.i. One fabric from front panels to center-back
  • Asteria 2.0 at shoulders, sleeves, center-back panel
  • Moovix compressive fabric from elbow to wrist
  • LoPro 30 arm, waistbands
  • Full CamLock reversed zipper

Dangerous in Heat

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

I don’t usually leave reviews, but I feel a duty to express how bad my experience was with this jersey. It does not breath well, better than a garbage bag but not good for hot weather at all. My first ride was in the upper 80s and about 15-20 miles in I was over heated and feeling ill. I tried a second time a couple of weeks later in the upper 70s with the same result. I had to cut my pace way down and ride home unzipped and I still don’t feel right yet. I have ridden plenty in hotter weather this year before and between those rides without issue. I used the black the first ride and the white one the second ride thinking that would make a difference. Because of the lack of breathability I believe they will just be clammy and wet in cooler weather. I seriously feel like the marketing on this jersey could put someone in a life threatening situation, do not buy it.

Very Nice

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

These run small. In Castelli I am snug in a Medium, but the Large Giordana fits just the same. The whole thing has a nice tight race fit, but the limited colors are a bit lame. In spite of that, the white still looks very TDF and I wear it in the hot LA sun so I don't need sleeves or extra sunscreen. One little snag in the fabric right away is a concern, still, I recommend these without question.

Heat Relief

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

This is my favorite jersey for the hottest days. It's very comfortable even on long rides. It's nice to not worry about sunscreen on my arms for the 4+ hour rides. It also does a great job keeping my upper body cool. I'm a more muscular build as typical riders go and I don't find the compression to be too much.

You have to use the fit guide. I found it to be accurate. It's a size larger jersey than I normally buy, but the fit guide called for that.

Great jersey!

  • Fit: True to size
  • Size Bought: XL

tight fit, got the XL. Feels like your are not wearing anything. Breaths really well. Rode 120 miles in it on a hot day and it preformed great.

Great jersey!

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

Bought this jersey to wear on the Death ride, 130 miles, 15K vertical feet of climbing. Worked as I expected, EXCELLENT!
Highly recommend for summer riding.

Surprised how comfortable and cool I am!

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

I bought a Large based on the suggestions of the other reviewers! Thanks since I am a medium in virtually all other jerseys! The wicking power of this jersey is amazing. Not coating my arms with sun screen is an added bonus! I have done several rides with temperatures in the mid eighties and I am very satisfied with my purchase. I am 5'9" and 165 lbs. for reference as far as the size goes.

Excellent quality but runs small

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

The jersey looks and feels great. The craftsmanship is outstanding. The only issue is that the size I ordered is way too small and tight. Traditional Italian sizing. At minimum, I recommend ordering one size up regardless of what the sizing chart outlines. I'm going to exchange the L to an XL (fingers crossed) and hope the fit is right. UPDATE: The XL had a nice race fit for me. I'm 5'10" 175 lbs 39" chest.

Runs small!

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: Runs small

Bought this as a Christmas gift for my father in law, but it runs really small! He's usually a medium but I got a large, and that was too small for him.

Wish they made more of these!

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

Innovative design allows you to wear this in 90F+ degree heat without getting overheated.

I'm allergic to many sun screen and this is the perfect solution for me--a long sleeve jersey for summer cycling!

Stays cool. I'm 5'7" and 125lbs and the small size fits well, although there are a few wrinkles--I wish it fit more like an aero jersey.

I highly recommend this jersey.

Luxury and performance

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

I have to say I've only worn this jersey once with the matching bib knickers and I powered through 98 miles no problem. This jersey feels like silky air when you put it on (reminds of the 2014 Silverline jersey that I also own). I wore it with an Assos springtime base layer and Capo wind vest in the early morning hours and I stayed warm. Maybe you would need more layering if it dips below 50-55. As for fit I've found Giordana jerseys to run long and a little loose in the midsection for my liking but I am a svelte 5'7.5" and 145 lbs. on a good day with a 29-30 waist and even the size small has some extra room. However, this jersey does not bunch up in the middle along the zipper on the bike which is nice. So the race cut on Giordana is a little more generous than the cut I have found in, say, Louis Garneau or Assos apparel. I'd highly recommend the bib knickers. If you're gonna drop $250 on a jersey why not treat yourself to the matching bibs? The knickers I can tell are going to become a favorite in my wardrobe as will this jersey. I purchased the white. Lastly, the long sleeves that provide compression also double as great protection on sunny days.

    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 the first jersey I reach for in my drawer. This is the first jersey I've ever worn that I immediately wash when I get home so it will be ready for the next ride. Guess its time for another pair.

    Fit is American, but slim with a wide chest. I'm normally Medium to Large and the Medium is plenty big.

    What's your height/build? I'm 6'1" & 185 pounds, and I prefer a slimmer fit.

    I'm 5'9 and a lean 165. It does run broad through the shoulders so take that into consideration.
