Castelli Gabba R Jacket 2026 waterproof cycling jacket

With its Gabba R Jacket, Castelli clearly meets the specific needs of professional riders. Part of the Rosso Corsa range, this high-quality jacket has been designed with meticulous attention to detail. Considered by the Italian brand to be the most protective and, above all, the most aerodynamic long-sleeved jacket ever made, it will allow you to ride as fast as possible whilst remaining protected from wind and rain. Tested in a wind tunnel to help you save watts even in appalling weather, this jacket is made from a waterproof fabric that hugs the body’s contours perfectly.

Lightweight and breathable, the Castelli Gabba R Jacket stretches in all directions to twice its size thanks to the 125 g/m² fabric, ensuring total freedom of movement. The inner lining in polyester and elastane enhances elasticity and breathability. The sleeves feature a special fabric at the cuffs to ensure a snug fit with gloves. At the back, the stretch fabric offers protection against road spray whilst ensuring better visibility via a reflective strip. This jacket features 3 mesh pockets to keep your belongings safe, with the mesh designed to repel water.
