Product details

The Alpha 150 W 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 features a close-fitting, stretchy design that allows freedom of movement without the feeling of wearing a heavy winter jacket. Additionally, the jacket is environmentally friendly, as it is made from recycled materials and is free of PFAS. The Alpha 150 W Jacket is the ideal choice for cyclists who want to stay active even in the cold season.
