The Castelli Alpha 150 Jacket is engineered for cyclists who demand comfort and performance in cold weather. Utilizing 12 years of continuous refinement, it combines the exclusive Polartec® AirCore™ outer layer with Polartec® Alpha™ insulation to maintain warmth while optimizing moisture management and breathability.

Designed with a close-to-body stretch fit, this jacket ensures freedom of movement without the bulk of a traditional winter jacket. It performs exceptionally on cold, dry days and can handle most wet conditions, though for prolonged driving rain, a dedicated rain shell is recommended. Recycled yarns and PFAS-free construction reinforce Castelli’s commitment to sustainable, high-performance cycling apparel.
