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 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 for free movement without sacrificing the protection of a winter jacket. The Alpha 150 W Jacket is ideal for cold, dry days and offers additional protection against light rain. Furthermore, it is environmentally friendly, as it is made from recycled materials and is free from PFAS.

  • Close-fitting, stretchy design for high comfort
  • Two large zippered pockets for secure storage
