If you're looking for a high-performance advantage in changeable weather conditions, Castelli's Gabba 2 Short Sleeve Jacket has you covered. More rain-jersey than cold-weather jacket, this short sleeved aerodynamic wonder provides lightweight warmth and windproof water-resistance with the Windstopper X-Lite Plus fabric. Nano Flex fabric inserts under the arms proved exceptional stretch and range of motion. A drop tail protects you from wheel spray and the three rear pockets have a unique drainage design to keep you and your things dry. The full-length front zip is sealed from moisture with a storm flap. Silicone grip on the waistband keeps the Gabba 2 in place, and reflective trim enhance low-light visibility.
