Story & heritage

Alpha 150 Jacket represents Castelli’s winter-protection side: a cold-weather road jacket for riders staying out when a jersey-and-vest setup is not enough.

Its official Castelli listing places it in the cold jacket category alongside the brand’s most protective road layers.

Materials & craft

The jacket is built with a high collar, long sleeves, protective front construction and pocketing for winter road use.

Official product photography highlights close sleeve finishing, rear-pocket structure and a clean outer shell designed for layered riding.

How to choose & style

Use it as the Castelli option for cold starts, long winter endurance rides and steady training days.

The black version is the easiest to pair with thermal tights, shoe covers and reflective accessories.
