The Alpha 150 Jacket from Castelli is a highly developed cycling jacket specifically designed for cold weather conditions. It combines innovative materials and a thoughtful design to ensure both warmth and breathability. The outer layer made of Polartec® AirCore™ protects against wind and rain, while the inner Polartec® Alpha™ insulation provides comfortable warmth. This jacket is the result of years of research and development aimed at optimizing comfort and functionality during winter rides. It offers a close-fitting, stretchy design that allows for freedom of movement without sacrificing the protection of a full winter jacket. Additionally, the jacket is environmentally friendly, as it is made from recycled materials and is free of PFAS. The Alpha 150 Jacket is therefore the ideal choice for cyclists who want to stay active even in the cold season.
