Everything you need to face cold winds and unexpected rain can be found in the Castelli Gabba 2 Jersey. Windstopper X-Lite Plus fabric is windproof and water-resistant, feels weightless against your skin, and has unprecedented stretch and breathability. It's also deceptively warm, yet doesn't overheat and gives you an aerodynamic edge. Thermal underarm panels and zippered side vents keep you dry, plus the longer back offers protection from wheel spray. Light like a jersey, but protective like a jacket, the Gabba 2 is the choice for intense aerobic activities in cool, wet conditions.
