The Gabba has earned its reputation as the piece that changed how cyclists think about wet-weather riding—not as something to endure, but as conditions you can actually perform in. Castelli's Gabba R Short Sleeve Jacket carries that legacy forward with Gore-Tex Infinium windstopper fabric that blocks wind and sheds light rain while breathing well enough that you're not swimming in your own sweat when you start pushing the pace. It's the jacket that lives in your kit bag from early spring through late fall, ready for those mornings when the forecast shows a mix of everything and you need one piece that handles all of it.

The short sleeve design makes more sense than it might seem on paper. Your core generates the heat, and that's where the Gabba R focuses its protection—wind and water resistance across your chest and back where you need it most, while your arms stay free to breathe and regulate temperature through your arm warmers or base layer. This modular approach means you're not locked into a single temperature window. Pair it with thermal arm warmers for near-freezing starts, strip down to bare arms when the afternoon warms up, and the jacket keeps working either way.

Gore-Tex Infinium sits at the intersection of weather protection and breathability that most fabrics can't reach. The membrane blocks wind completely and handles light precipitation without the clammy feeling you get from fully waterproof shells. Castelli cuts the Gabba R in their race fit—close enough to eliminate flapping at speed but with enough room for a base layer underneath. The raw-cut sleeve edges sit cleanly against arm warmers without bunching, and the dropped tail provides coverage in the riding position without excess fabric when you're standing upright....
