Castelli Alpha Flight RoS Jacket

The Alpha Flight Rain or Shine Jacket is one of Castelli’s fastest jackets for cool weather races with scattered rains. If it does rain, the Alpha Flight will keep you dry and warm. Besides repelling rain, the cycling jacket is lightweight, fabulously breathable, and extremely fast. The Alpha Flight is one of Castelli’s best race jackets. On front where you get most wind chill, the Polartec® Alpha insular fabric keeps you warm with minimal weight. The Polartec® keeps you warm, but circulating air ensures you don’t overheat. On back, the Nano Flex Light woven fabric blocks wind and a water-repellent finish casts off rain, yet without a membrane. Porous construction keeps you comfortable by allowing air to circulate, yet without compromising protection from cold wind and rain. Castelli designed the Alpha Flight RoS Jacket for high intensity training rides and races. Features such as raw-edge waist and three rear pockets with laser-cut drain holes add to a performance piece of cycling clothing that keeps you streamlined in an aero position while maintaining as much comfort as possible when racing in unfavorable conditions.
