The future of cycling is here.

One simple piece of gear can easily change the way you race in the rain. And cold. And ride in training. Every other performance cyclist soon saw the need for a Castelli Men's Gabba RoS in their wardrobe, why not join the pros yourself?

This fourth-generation Gabba is as close to perfection as possible. A new and improved composition involves top-of-the-line water resistance, which meant utilizing the exclusive GORE-TEX INFINIUM™ WINDSTOPPER® fabric. The front-facing fabric was made warmer with a light brushing, while the rear-facing fabrics are lighter yet more water repellent than the previous Gabba. Seam sealing on the shoulders and a covered zipper makes this top more equipped for the rain than ever before. Thanks to Team Ineos testing, the two durable pockets are easier to access with gloved hands, though an internal sleeve is provided to keep your pump or other items from moving around.

Starting with a clean slate, a significant upgrade has been made to the previous Gabba to boost the heavy-duty nature of an already incredible item. With the Castelli Men's Gabba RoS, take the challenge and train for your best self — crushing the competition rain or shine.
