Castelli Alpha jacket review£250.00

Superb winter jacket with a glove-like fit

BikeRadar score5/5

The Alpha brings innovation to winter jackets, and plenty of style. Stretchy Windstopper 150 fabric creates the windproof, water resistant shell but, rather than a conventional softshell material, Castelli has detached the insulation, and only added it where necessary.

The back has a mesh panel and ventilation flap and most of the sleeves have a warm waffle pattern fabric, as does the zip-up waistcoat that insulates the chest. It’s fixed at both sides, but if you overheat, the Alpha allows you to open the main zip to expel moisture without chilling your core.

All the insulation moves independently of the shell, giving great freedom, and Castelli’s raw edge cuffs and waistband seal perfectly, lying totally flat for excellent glove-like fit and no draughts. Even the articulated collar is super snug. Practicalities are taken care of by three drop pockets and two zipped, one rear and one on the waist.

Robin began road cycling in 1988, and with mountain bikes in their infancy, mixed experimental off-road adventures with club time trials and road races. Cyclocross soon became a winter staple, and has remained his favourite form of competition. Robin has always loved the technical aspect of building and maintaining bikes, and several years working in a good bike shop only amplified that. Ten years as a Forensic Photographer followed, honing his eye for detail in pictures and words. He has shot at the biggest pro events since the '90s, and now he's here, drawing on all those experiences to figure out what makes a bike or component tick.
