Let your body ignore the rain.

When the rain is an inevitability for your upcoming ride or race, you're typically left with no choice but to reach for the translucent, flappy rain jacket or the hot, stuffy long-sleeve jersey. The Castelli Gabba WS Long Sleeve Jersey comes along to solve that problem, combining an aerodynamic, race-ready jersey with some remarkable materials into a particularly smart piece.

Developed closely with the Cervelo Test Team pro squad, the long-sleeve version of the Gabba you see here was conceived as a rain-specific version of the Castelli Aero Race Jersey. The cut is very similar, but the materials used in the Gabba are notably different. First, the experts at Gore were consulted to craft an even lighter, more breathable, but more weather-resistant version of their famous WindStopper fabric, and the result is the WindStopper X-Lite Plus material that comprises the jersey's primary body panels (hence the WS designation in the title). X-Lite Plus has an uncanny ability to shed wind and water - fun to demonstrate by pouring some liquid onto the jersey and watching it simply roll cleanly off. Combined with the material's excellent interior moisture management and breathability, you can ride for hours without accumulating either sweat or rain on your skin and pull off the jersey as dry as you put it on.

Smart details abound in the Gabba long-sleeve jersey, too: to further that breathability and ensure that the jersey allows freedom of movement, Castelli's NanoFlex fabric is used on the side and underarm panels. There's a storm flap panel on the rear to prevent exposure to wheel spray, and the three rear pockets even have eyelets to help drain any accumulated water. Finally, there are zippered chest vents to help cool you down if it starts to get muggy out. All told, pro rider Roger Hammond called it the best jersey he's ever worn - a heck of an endorsement if we've ever heard one.

The Castelli Gabba WS Long Sleeve Jersey is available in six sizes from Small to XXX-Large and in colors Black/reflective silver and Yellow Fluorescent/reflective silver.

Here's what others have to say...


Not a Castelli fan, but I love Gabba

  • Familiarity:I've put it through the wringer

This is a fabulous top. I have used it alone down to the low 40s, and with a base layer to about freezing. Light rain has been no problem, and the little chest zippers provide some noticeable venting.

Sizing is very slim -- I'm 5'9", 155 lbs and the large is compressive around the torso but slack on the arms. If you don't like that fit, look elsewhere.


Almost perfect, beside the size...

    Fits and feels perfect without a base layer. Would definitely recommend a base layer! Got it in size XL and need to size up XXL. Im 6�3", 190lbs, 34/34 pants athletic shape.
    Find the reviews very informative, that?s why I�m submitting my 50 cents :-)


    Rain, halt, sleet, or snow

    • Familiarity:I've put it through the wringer

    I have used this jersey in all of the above conditions and it has preformed excellently in all cases. When paired with a heavy base layer this can be worn at near freezing temperatures but also does not fail at 50 degrees. Excellent all-season jersey!!


    Single Favorite Jersey

    • Familiarity:I've used it several times

    I love this piece! First, the sleeves are plenty long for my arms. Wish more companies had similarly longer sleeves. The fabric has a bit of thickness/heft to it, and when you ride, it does not flap around, BUT, the jacket conforms to your body. Also, it has a flap that is basically a drip edge for your rear - useful in the rain. Venting zippers, nice cut....a super jacket. I'm guessing with a base layer under it, you could go down to 40F or less here in (damp, wet) New England. Yes, it is expensive. I hope Castelli expands this line of clothing, I'm sold. I am 5'11", 155lbs, long arms and the L fits great.


    Fits tight

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

    Just got it in the mail today and quality is top notch Castelli. I haven't had a chance to take it in the rain yet (unfortunately?) but the fit feels perfect. That being said I did have to size up. I'm 5'10 @ 158lbs and I had to get a Large. I usually wear a medium everything, t-shirts, jerseys, ect and I am very happy that I got the Large. It's still a tight fit, but is what I would expect. Chest is about 38.5. The yellow looks much better in person. Typical neon green and the red castilli logo looks great. Grab it up if you spot a good deal while you can.

    • Fit:Runs small

    I'm not one to typically write reviews, but read them and bought this jersey based on the positive feedback. I am absolutely in love with this jersey! Did a very cool 44 deg. Sunday morning ride a tighty-whitey t-shirt base layer. This aero Gabba kept me toasty, and I even had to unzip the nicely located abdominal vents to dump heat.

    Did I already say that I love this jersey?!?!



      I will preface this by saying that I am not a big fan of Castelli clothing in general.

      That being said, the Gabba is a super piece for training gear. With a base layer, it works down to at least 40 degrees. Good race fit (I'm 5'11", 40 chest,32 waist, Size L). It's waterproof enough for me. I also own the short sleeved version in black. Reasonable price for what you get.

      Im looking for this black, s size.

      When is it available again?


      As of right now, we do not have any more of the Black/S ordered to come in. Sorry about that!

      Unanswered Question

      From the reviews it is hard to tell how "warm" these are. If truly "warm" I could see the L/S having a role, but if not the short sleeve with warmers would be nice provided that one would want to wear the SS by itself on a training ride.....

      i have a gabba long sleeve jersy,but in a...

      i have a gabba long sleeve jersy,but in a heavy cold rain do i need a top layer say castelli muur or something similar


      Short or fast ride / race -- Gabba. The effort will keep you warm.

      Long or slower or cold weather -- more layers or heavier jacket.

      I live in SF and ride in winter rain or shine. It gets down to around the high 30s and low 40s with lots of wind and I use a 100% merino short sleeve or tank top as a baselayer. The only time I have gotten a bit cold is when I am riding in the rain for one hour plus in driving rain. There is no seam seal so the water will get in eventually.


      Love it!

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

      I'm 6'2" and weigh about 190 lbs. The XL fits me perfectly. I wore the black one over two rainy Seattle winters ago and i liked it so much that i bought the yellow fluorescence one as well. On near freezing days, so i need to do is the wear this with one base layer and that would keep me sufficiently warm. The Gabba jersey is not completely waterproof and eventually it will get wet but if you have a base layer, you should be ok.


      My favorite foul-weather piece

      • Gender:Male
      • Familiarity:I've put it through the wringer

      Outstanding quality and amazing versatility. Superior wind and water protection. It isn't waterproof but it will keep you dry in all but a downpour. The cut is fantastic - no flapping in the wind but enough room to layer up, the extra long tail keeps you covered in the drops, and the neck is snug enough to keep the wind out but doesn't choke. Vents extremely well thanks to the 2 large side zips. I like the reflective striping on the back and the drain holes in the rear pockets. I've worn it in the 50s with a light base layer, all the way down to the low 30s with a UA thermal mock turtle neck or IceBreaker merino wool layer. Highly recommend. 5'11, 160lbs, 38.5" chest, 30" waist. SIZE L fits me perfectly.


      Had to return it, too small.

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

      My measurement should have provided room to spare according to the size chart. Well it didn't, it's too small. Great service form Backcountry to arrange the exchange for a larger one.

      I got the replacement size and tried it today.

      It was 10�C (that's 50�F to US folks) and a fairly good shower. I'm impressed, I felt comfortable all ride long, no overheat, not cold and dry. I had just a base layer underneath it. So farr it's just what I've been looking for for a long time.

      is pairing this up w/ the Gabba vest...

      is pairing this up w/ the Gabba vest overkill?

      I'd say this jersey is best for layering underneath it, not over it. If you were to put something over the Gabba Jersey, it would probably be a rain jacket that's light and more waterproof.


      Just a great jersey/jacket

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

      I have the version of this when it was called the Aero Rain Jacket, same thing as Gabba except it was before they added the front zips.

      The windproof-yet-breathable capability of this thing is astounding. Just perfect in 30 to 40 degree temps with a base layer or two, and you stay aero. I can really feel the difference between wearing this and a fuller fitting jersey or jacket. With aero wheels I usually have to talk myself into perceiving their advantage, not with this thing, the advantage is front and center.

      A word on sizing which seems to be concerning or confusing some people. Forget about whether to "size up", or how tall you are, or your weight or waist size. Just take your chest measurement and use the Castelli sizing chart, you'll get a perfect fit, couldn't be easier (I've found that true for just using waist size for their bibs as well).

      The most brilliant piece of cycling equipment I own.

      **Update 8/2014**

      I liked this jacket/jersey (Aero Rain Jacket version) that I bought a Gabba SS jersey, large. Couple observations: while the LS Aero Rain Jacket is cut perfectly for me from top to bottom the Gabba SS jersey has more room around the waist while still being just right in the chest, it puckers a bit so not the perfect aero fit of the LS jersey. My Aero Rain Jacket also does not suffer from baggy arms as some reviewers here have noted for the Gabba LS. So it seems the Aero Rain is a slightly different product from a fit perspective, those looking for a the most form fitting version of this technology might consider it instead of the Gabba. Or perhaps the new Gabba version has slimmed down a bit from V.1.


      Works for a wide range of temps

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

      I've ridden this from 50 degrees and pouring rain down to the mid teens. Some reviews claim that this is near waterproof, however, it really isn't. When you first start riding in the rain, the water quickly beads off, however after 10 minutes or so, it starts to soak into the fabric. That being said, it is still way better then being cold and wet with a more standard jersey, or hot and steaming with a PVC rain cape. After one 3 hour ride in pretty nasty wet conditions (upper 40's), my inside jersey was pretty wet, however, I was still warm/comfortable.

      As for what it is, its not really a jersey, as its more of a jacket. Where it really shines is for wind resistance. It really cuts the wind keeping you warm, however, it really does breath unlike my older "Tech" coat from 3 years ago which would leave me clammy after anything over 1 hour of hard riding.

      In the winter, this jersey/thing is great for layering. For my mid teens (wind chills in the 0-neg 10 range) 2 hour ride, I rode a Helly Hanson Warm base layer (also a great piece of gear) a thin roubaix fleece lined LS jersey and this, and was content. When I finished, feeling all the layers, everything worked. Stayed dry and warm.

      Now the fit: its race cut. This is exactly what I was looking for. I wanted a coat that I could actually race in and not be worried about being a parachute. I'm 150 lbs, wear mediums in most bike tops, smalls in most bike jackets, S and XS in most consumer cloths. I bought a medium and it fits pretty much as advertised. Almost tight, yet its flexible enough where you don't feel cramped. I've actually raced probably 10+ late fall races in this jacket and never felt over or under dressed.

      I did a lot of reading before I spent the cash on this jacket, but in the end, I'm glad I did. I really like this jersey and ride it all the time.


      Best jacket I've owned to date!

      • Familiarity:I've used it several times

      I absolutely love this jacket! Totally windproof yet breathable. The side vents help when the temperature rises during a climb or a long ride that started out chilly. Note that it's a windproof shell so you may still need some layers underneath (I assume it's great in the rain too but I've been blessed so far not to know yet). If I'm riding at 5C (40F) or less, I'll usually wear two base layers and a short sleeve jersey under it. It's light, the arms are longer than what you typically get on a long sleeve garment (great for me since I have long arms) and there are 3 deep pockets on the back. I usually wear a medium-sized Castelli jersey but found I needed a large size in this jacket. My chest is 38in. Still has a nice and snug/aero race fit (i.e. no loose fabric flapping around in the wind).

      Have been riding this jersey here in the PNW for the last few weeks. Temps have ranged from high 20's to mid 40's with some rain/sleet in the mix. Jersey has been great in all conditions, though I am using a mid-weight merino base layer. Only complaint is the arms are cut a bit big considering how well fitted the body is (and how slim cyclists arms can be). I did size up due to recommendations, and feel it was necessary. Still a great buy, definitely one of my favorite pieces of kit.
