Our full review
The Castelli Gabba ROS Jacket stands as one of the most trusted names in cycling outerwear, bridging the gap between a jersey and a rain jacket for riders who face unpredictable weather on every outing. Built with Castelli's signature Gabba fabric, this jacket combines a windproof, water-resistant front panel with a breathable, stretch mesh rear, allowing cyclists to stay protected from wind, drizzle, and road spray without overheating during hard efforts. The ROS designation, standing for "Road Race," reflects its race-ready pedigree, having been developed and refined through feedback from professional peloton riders who demand performance without compromise in variable conditions.

Fit is everything with the Gabba ROS, and Castelli has tailored this jacket with a race-cut silhouette that hugs the body closely, reducing aerodynamic drag while still allowing full freedom of movement in the shoulders and arms. The stretch side panels and gusseted underarms ensure that reaching for the drops or climbing out of the saddle never feels restrictive, while the elasticated hem and cuffs keep cold air and moisture from creeping in. A full-length front zipper with a wind flap adds an extra layer of defense against gusts, and the collar is cut to sit comfortably against the neck without chafing, even when zipped all the way up on a chilly descent.
Practical details round out the design, making this jacket as functional as it is technically advanced. Three rear pockets provide ample storage for nutrition, tools, or a spare layer, while reflective accents on the back and sleeves boost visibility during low-light rides, whether at dawn, dusk, or under overcast skies. The versatility of the Gabba ROS Jacket makes it a year-round staple for serious cyclists, equally at home in early spring training rides, damp autumn group rides, or as a lightweight shield against unexpected showers in summer. Its reputation among racers and dedicated amateurs alike has cemented it as a go-to piece of Cycling Gear for anyone who refuses to let the weather dictate their ride.
