Ride in the rain.

If it's race day and the rain is coming down in buckets, you obviously need to stay dry to win. Instead of throwing on a flappy jacket, gain an advantage over the pack with the Castelli Gabba WS Jersey. The Gabba WS jersey was designed hand-in-hand with the Cervelo Test Team and the Garmin-Barracuda cycling team to create an edge against the brutal weather of the spring classics. The Gabba WS fits and feels like Castelli's Aero Race jersey, but with all of the weather protection of a rain jacket.

The Castelli Gabba WS Jersey is a rain-specific version of the Castelli Aero Race Jersey. In the development stage, Castelli knew that no material existed to meet Cervelo Test Team's demands for a rainproof race jersey, so a partnership was formed with W.L. Gore to create the new WindStopper X-Lite Plus fabric. The new four-way stretch fabric allowed the construction of the form-fitting, windproof, and breathable rainproof jersey that we have today. For further rain protection, Castelli included a storm flap off the rear jersey panel to protect you from wheel spray, and the three rear pockets feature eyelets for water drainage. To add extra comfort, Nanoflex inserts under the arms and zippered chest vents allow controlled temperature regulation and a better fit. Castelli finished off the Gabba with a silicone gripper at the waistband to control jersey creep and rear reflective tabs for enhanced visibility in gloomy conditions. The end result of all this innovation is a jersey that Roger Hammond calls the best jersey he's ever worn. You can't go wrong with that.

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

What they said...

  • Familiarity: I've used it several times

I just wanted to echo the previous reviewers. This jersey is perfect for cold weather rides. I prefer the minimalist aesthetic of Rapha (Castelli seems to be turning into the Abercrombie of cycling apparel, plastering their name and logo everywhere); that said, the Gabba is awesome.

best jersey I've owned

  • Familiarity: I've put it through the wringer

I bought this last fall and it is easily my favorite jersey for riding in temps ranging from the mid-30's to mid-50's layering accordingly. Unlike most thermal jackets the Gabba is super comfy and repels water like no other. I originally purchased a medium (my normal size) however it was too snug. You might want to size up.

Awesome pre & post winter jersey

  • Familiarity: I've put it through the wringer

This Gabba product is awesome cold weather riding jersey. I wore craft short sleeve base and Gabba jersey with 2 arm warmers for each arm so I could pill it down 1 by 1 as it gets too warm (should try this) while other riders had at least 3 + layers of protected tops to keep them warm. Gabba gives freedom and tight fit like a race jersey and looks of pro rather than a bulkiness and restricted movement with layering! over heating = poor performance ^^

I am ordering new Gabba 2 Jacket for this winter!

A Great Jersey

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

Warmth and rain protection in a short sleeve jersey. This is my go-to top for fall and spring time riding. Pair it with arm warmers and you will be as comfortable as can be. This is a great product that filled a niche pacific northwest riders were craving. Castelli.... I salute you.

Gabba Gabba!

  • Familiarity: I've put it through the wringer

Very nice piece. I like it when it is dry, 60 and windy for my short sleeve Gabba. If it's raining... the quality really shines through with complete water/wind proofing on the shoulders and torso. It zips up snug to the neck to keep out the rain. I also like throwing an Uno base layer underneath this to get another 10 to 15 degrees colder of wear out of it. It's like an urban scuba jersey.

Gabba Gabba!

Protective and warm, but not too warm.

  • Familiarity: I've used it several times

The cut of this jersey is great--very comfortable and I love the fact that the rear flap is a bit longer to cover your butt in foul weather. Perfect for crisp, cold, and damp fall days when coupled with some arm warmers. This has been one of my favorite pieces of equipment, until today when I crashed while sprinting at well above 20 mph. I landed on my back and slid a long way. The jersey, although damaged, did a great job of protecting my skin (see attached). I walked away with a couple of scrapes and a slight concussion, and will be purchasing another one of these.

Protective and warm, but not too warm.

Lives up to the hype

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

I live in the NW where the weather more often than not includes precipitation. Some days its cold and some days its mild so it's always a struggle to figure out what to wear without overheating. The Gabba WS Jersey paired with the nano flex arm warmers is so versatile that it completely eliminates the internal debates. The jacket is water resistant but the coating causes water to bead up and fall off making it practically waterproof. The sleeves are long and come down to just an inch above my inner elbow giving more than adequate coverage to keep the upper arm warm. As mentioned above, pairing with NF arm warmers give you full length coverage to your palms. The jersey has a full zip so as you start to warm up you can unzip as necessary or go fully unzipped and rid all your core heat. The collar is soft and stays in place. The zipper is easy to grab with gloves on. The pockets are easy to access and the open rivets allow water build-up to escape. The butt flap can be folded inside of the back of the jersey when it's not needed or whip it out for extra coverage from rooster tails. My only knock is that the sizing is tricky. It's an italian brand so expect this piece to have smaller than normal sizing. I had to order two sizes and return the other to ensure proper fit. I ended up opting for one size larger than I normally use.

Perfect for varied weather conditions, cold winds, showers etc. Replaces the gilet but comes with better wet weather protection than most vests. Have found it works in a wide range of tempretures as well, I can wear it in the dark morning training session with wind and showers and then ride home from work in the sun and still not suffer.

Unlike other reviewers I found the zip to be fantastic, nice large teeth - good friction and an inch of travel really brings in a lot of fresh air.

Have climbed up mountains with the jersey undone and then zipped up for the descent - excellent.

Best piece of apparel I've purchased in years - if you purchase this make sure you get the nano-flex arm warmers too, they really do work well together. (the shorts and knee warmers aren't as good as the jersey and armwarmers, not everything Castelli do is brilliant)

Works great but watch out for sizing.

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

I have used this jersey a couple times now in extended rain rides. Works as advertised, the water beads off and you stay dry. I normally wear a size L Castelli with their race cut. Size medium in their club cut. For this jersey, I needed a medium. The large was way too baggy in the chest and gut with a single thin base layer.

Best Jacket I've ever owned

  • Familiarity: I've used it several times

I have the long sleeve which you can actually take out the sleeves and end up with a Jersey, normal sleeve length. I use it from about 25F to about 44F. In the 20's and 30's F I use it with a base layer and a mid layer, with temps above 40 or in the 40's I used it only with a base layer, and it works Perfect! I've used in conjunction with the Castelli Sorpasso Bib Tights and its perfect!

I just finished the Rapha/Strava 500Km Challenge in December, I could not have had better gear!

I've put them in the washing machine, under delicates, not too much detergent and washed them about 10 times, everything looks brand new.

I'm 6'0, 174lbs and I have an XL size, I could have worn a Large, but then limit myself to only one layer. XL allowed me to be able to wear two layers underneath.

Best Jacket I've ever owned

The Best

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

This is probably the best item of clothing I have bought. Castelli always seem to get it right. I wore it for the first time today, it was about 55 degrees and pretty breezy. I wore this with a thin sleeveless baselayer and the nano flex arm warmers, and to be honest was a little warm! This is going to be perfect later in the winter when it gets below 50

The right protection

    What makes a great piece is when it comes to work and does it's job. That is exactly what the Gabba will do. This is for those days that mediate on a temperate roller coaster yet the wind accents the weather to make it necessary to cover up and ride through it. Not the piece I am riding straight into a rainstorm with but greta for fall rides with a merino base layer or spring warmups with some wind. Fit is amazing with dropped rear. Say butternut squash soup and I am there.

    Works as advertised!

      Got caught in a driving rain in 50 degrees (F) for over an hour and my Gabba kept me warm and dry. Fabric can get a little clammy next to the skin on its own, so I usually wear at least a light mesh base layer under it, which gets rid of that problem. I find it breathable enough for most situations, and of course it's got a full length zipper for regulating temps. It's definitely more wind resistant than a conventional cloth jersey, and that's a real plus, but not totally windproof like full Gortex, That's Okay because it lets it breath. On really windy, cold days, I use a Craft base layer with windstopper on the chest for additional wind protection underneath. Its great having a jersey like this on when you leave home and there's a chance of rain. Don't have to pack a full rain jacket just in case and the Gabba is more streamlined and doesn't billow about.

      I have used it regularly this Fall/Winter here in Colorado in temps down to the high thirties with arm warmers and a good base layer. Unless you know you are going to be riding on a rainy day, this is not a warm weather summer jersey. This is more of a three season Fall Winter Spring classics type for temps below about 60 degrees F. Rear pockets are very deep, which is great for storing additional layers on transitional days. Sleeves are longer than usually found on a short sleeve jersey, which means there's no gap between the top of your arm warmers and the jersey sleeve on cool days. The extended flap on the back is great for keeping your butt dry in wet or slushy conditions.

      Like it, but not sure it's a

        Jersey has its merits, but it's not as good as it's made out to be.

        Two big problems. First, it really doesn't breathe all that well. The wind resistant fabric is on the back as well as the front, plus it has no zippered vents, unlike many wind jerseys. Plus, it wicks very poorly. Not as bad as a wetsuit, but heading in that direction. If you're a GC rider on Garmin Cervelo with zero mass in your upper body, maybe you can stay cool. Otherwise, maybe not.

        Second, the jersey is very elastic, and that extends to the zipper backing as well. So trying to zip/unzip with one hand is very hard. Like pulling on a rubber band. And if you leave it more than 1/3 unzipped, it catches wind like a sail. 1/2 unzipped on a descent and it unzips itself to the bottom, then sticks, becoming a parachute.

        So I find it's a great top layer when it's really cold. If you're like me, over one or two base layers/arm warmers, I'm comfortable into the low-30's. Get into the upper 40's and I start to feel really uncomfortable.

        Quality and aesthetics are great, by the way. If you take it as a short sleeve jacket for very cold conditions, it's really nice.

        Great windstopping, very wrong colors

          As typical with Gore's windstopper fabrics, does a great job in that regard and although couldn't test it's rain shedding abilities, will trust as typical for WS. However for a designated 'rain' jacket the color choices are dreadful: 'kill me black' or show all rain spots forever white... ugh. When it's raining and the asphalt pavement is glistening and black, I don't want a glistening and black jersey which is essentially asphalt camoflauge. Sure white is more visible and the safer choice but any poly white fabric will grab and hold stains forever. Please make this jersey in bright red, Cyan blue or yes... flour yellow and it will be perfection.

          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.....
