Castelli Alpha 150 Rosso Corsa Windproof Cycling Jacket Burgundy Women

The Castelli Alpha 150 Rosso Corsa windproof jacket Women is designed to keep you riding throughout the winter. It is the result of 12 years of continuous refinement of a concept engineered to keep you warm and dry, inside and out.

New for 2025, the Alpha 150 now uses Castelli’s exclusive Polartec Air Core 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 it doesn’t feel like you’re wearing a full winter jacket. This jacket is ideal for cold, dry days, but it can cope with everything except all-day heavy rain, in which case you will probably need a waterproof.
