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.

They made some minor updates along the way, but for the fourth-generation Gabba Castelli started with a clean slate to make a significant upgrade. That involved moving it to water resistance, which meant developing a new exclusive GORE-TEX INFINIUM WINDSTOPPER fabric. The front-facing fabric is warmer with a light brushing, while the rear-facing fabrics are lighter yet more water repellent than the previous Gabba.

It's better in the rain through seam sealing on the shoulders and a covered zipper. Based on Team Ineos testing and feedback the rear has two pockets that are easier to access with gloved hands, but still with an internal sleeve to keep your pump or other items from moving around.

WHAT IT IS

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 Nano Flex arm warmers, it allows you to keep your core warm without overheating.
