Now in a fully printed graphic version! This is the original jacket/jersey that started an entire new product class: the Gabba. It's a water-resistant short-sleeve jacket that's equally ideal for dry conditions. Made to be worn with our Nano Flex arm warmers, it allows you to keep your core warm without overheating.
- The 4th generation of the Gabba from the inventors of the Gabba
- Now more water resistant than ever
- Castelli exclusive GORE-TEX INFINIUM™ WINDSTOPPER® 205 Warm brushed water resistant fabric on front-facing surfaces
- GORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch on rear-facing surfaces for extra stretch and breathability
- Taped shoulder seams (reflective for color 085) for extra rain protection
- YKK® Vislon® zipper for easy sliding, covered for extra wind and rain protection
- 2 rear pockets with pump sleeve are easily accessed with gloved hands
- Dropped tail with large black reflective panel
HOW COME NO ONE EVER MADE A BETTER GABBA?
In 2010 Castelli introduced the Gabba to the pros and changed the way pros race in the rain. And cold. And ride in training. Every other performance cyclist soon saw the need for a Gabba in his or her wardrobe.
We've made some minor updates along the way, but for the fourth-generation Gabba we started with a clean slate to make a significant upgrade. That involved moving it to near waterproof levels, which meant developing a new exclusive GORE-TEX INFINIUM™ WINDSTOPPER® fabric. We made the front-facing fabric warmer with a light brushing, while the rear-facing fabrics are lighter yet more water repellent than the previous Gabba.
We made it better in the rain through seam sealing on the shoulders and a covered zipper. Based on INEOS Grenadiers testing we figured it's better to have two pockets that are easier to access with gloved hands, though we provide an internal sleeve to keep your pump or other items from moving around.
It's not easy to make a better Gabba. We'll keep trying.

How to Measure
- Chest: measure horizontally under the arms around the fullest part of the chest.
- Waist: measure horizontally around the natural waistline, keeping the tape slightly loose.
- Hips: measure horizontally around the fullest part of the hips with feet together.
- Inside leg: measure a well-fitting pair of trousers from the crotch seam to the ankle.
- Hand circumference: measure around the hand using a tape measure or a piece of string and a ruler.
- Bra: measure bust at the fullest point and underbust directly below the bust.
Fit: Castelli specialises in performance cycling apparel and many garments have a close-to-body fit. The manufacturer's general rule is to choose the larger size when your measurements fall between two sizes. Product-specific fit guidance always takes priority.
