The Alpha 150 cycling jacket, developed over 12 years, combines premium fabrics and innovative construction to keep you warm and dry in all conditions.
Its outer layer features Polartec® AirCore™ 150g—an exclusive Castelli fabric—which blocks wind and rain while offering market-leading breathability. Inside, Polartec® Alpha™ insulation provides significant warmth with extremely low weight and optimized moisture management. Thanks to its stretchy, close-to-body fit, you’ll forget you’re even wearing a winter jacket.
Ideal for cold, dry days, it also handles most weather fluctuations—though a dedicated rain jacket remains preferable for continuous heavy rain. Finally, the use of recycled yarn and a PFAS-free design rounds out the package.
