Castelli Alpha 150 Jacket XL Black / Black

The Castelli Alpha 150 Rosso Corsa windproof jacket is designed to keep you riding throughout the winter. It is the result of 12 years of continual refinement of a concept devised to keep you warm and dry, inside and out. New for 2025, the Alpha 150 now uses Castelli’s exclusive Polartec AirCore fabric to deliver unrivalled breathability in a windproof and waterproof fabric.Inside, Polartec Alpha insulation provides warmth and reduces moisture. The stretchy, close-to-body fit means you do not feel as if you are wearing a full winter jacket. This jacket is ideal for cold, dry days, but can handle everything except all-day heavy rain, in which case you will probably need a waterproof.
