    Advanced is an understatement.

    Relegating lesser jerseys to dusty storage bins, the Giordana EXO System Long-Sleeve Jersey is packed with more technical innovation than most anything on the market today. Engineered for warm-weather wear, the EXO System's A.i. One fabric actively wicks moisture with its special inside weave and lightweight outer layer. This not only keeps you utterly cool and comfortable when the mercury skyrockets, but it also protects you from harmful UV rays. Add in Asteria 2.0 fabric along the shoulders, sleeves, and center-back panel for enhanced thermo-regulation and an extra-slippery profile that cuts through the wind with the utmost efficiency.

    Compressive Moovix fabric spans from the elbow to the wrist, helping to dissipate road vibration and excess feedback from fatiguing your muscles. Kite Mesh around the lower back and underarms wicks moisture where you sweat most, while the LoPro 30 arm and waistbands provide a secure fit at high speeds. Preventing bulging pockets from jostling at speed, Host Carbon fabric bolsters the rear pockets. Moreover, you'll appreciate the no-profile collar for its skin-suit like effect, as well as three rear pockets for ample storage of extra layers and energy gels.

    Dangerous in Heat

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: XL
    • Height: 6'0"
    • Weight: 170lbs

    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
    • Height: 5'7"
    • Weight: 159lbs

    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
    • Height: 6'3"

    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
    • Height: 5'11"
    • Weight: 175lbs

    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
    • Height: 5'0"
    • Weight: 165lbs

    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!

    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.
