The Alpha 150 Jacket from Castelli is an advanced cycling jacket designed for cold weather conditions. It combines modern materials and sophisticated design to provide both warmth and breathability. The outer layer of Polartec AirCore protects against wind and rain, while the inner Polartec Alpha insulation provides cosy warmth. This jacket is the result of over a decade of research and development to optimise comfort and functionality for winter riding. The Alpha 150 Jacket is good for cyclists who want to stay active in cool temperatures without sacrificing comfort. It offers a close, stretchy fit that makes wearing a winter jacket almost unnoticeable. The jacket is also environmentally friendly, as it is made from recycled materials and is PFAS-free.
