Alpha Flight Ros Jacket Castelli's ultimate jacket for mild conditions - a lightweight, breathable, and fast option perfect for high-intensity rides or maintaining the ideal temperature in cooler weather. The Nano Flex Light woven fabric strategically placed on the chest, sleeves, and upper back provides partial wind resistance, prioritising breathability. The innovative Alpha double-layer construction effectively manages ventilation and temperature by separating the wind-blocking layer from the insulation layer. Topped with a water-repellent finish and featuring Polartec® Alpha active insulation, this jacket keeps you warm where it counts. The addition of Nano Flex Extra Dry on the back offers enhanced ventilation, allowing heat and sweat to escape while fending off rain with its nanotechnology water-repellent finish.
