Item # GIO0450

In search of the grail.

The EXO System jersey is Giordana’s attempt at the ultimate cycling jersey—a balanced blend of comfort, support, and aerodynamics. In pursuit of this goal, Giordana designed the EXO with five different fabrics, strategically located to provide that balance.

The front panel is made with Giordana-exclusive A.I. One. This is a two-filament fabric that creates air pockets between the skin and the material to provide a cooling sensation. A.I. One also provides omni-directional stretch for a perfect fit that won’t bunch up.

The fabric used at the sleeves and shoulders is Asteria 2.0, which has the highest threads-per-square-centimeter ratio in the cycling industry. Not only is the fabric incredibly soft to the touch, it provides support (not quite compression, but similar) to your upper arms, which absorbs most of the road vibration.

At the rear, Giordana uses Host Carbon—the same fabric used in its FormaRed Carbon pieces. This is an extremely breathable honeycomb knit fabric that also provides omni-directional stretch for a perfect fit and near-perfect aerodynamics.

  • A.I. One front panel
  • Asteria 2.0 shoulders and sleeves
  • Host Carbon cuffs and waistband
  • LoPro 30 pocket, underarms, ventilation
  • No-profile integrated collar
  • Three rear pockets with aero flaps

Expected more

  • Familiarity: I've put it through the wringer

I have used Giordana for several years now and would put the FRC line up against anything, truly great stuff. So when the EXO came out I was excited to see what improvements had been made. The arms are snug, long, and aero, no complaints there. The body material is comfortable but I was expecting a snug race fit, like a second skin, not the case here it tends to bunch up. It is also very long in the torso, much longer than the FRC jerseys. Hanging down almost mid rear-end with a couple things in the pockets. They also put a "flap" over the top of the pockets, I suppose it helps keep things in but it also makes it hard to get at items. Branded as a game changer, especially for the cost, I expected better. I'll stick with the FRC line. The bibs are a different story, but that's a different review, they are however fantastic.

Perfect Jersey

  • Familiarity: I've put it through the wringer

By far the best jersey I've ever owned. The fit is great. Tight and still long enough. I'm 6' 1" 185lbs and I wear a large. Other jerseys just feel cheap compared to the exo. Well worth the money.

Too tight in the arms for my size

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

Used it on 2 rides. The shirt fabric is great but I don't like the elastic on the arms at all. It is way to tight for my body type (athletic, 6'-3"' 195lbs). I bought size XXL, and with other brands I use that size would be ok on chest/arms, normally wide on the waist.

They should use a more forgiving elastic for the arms. No need to have it so tight for an XXL size.

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.

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