The Alpha MC Studio Jacket takes Castelli’s favourite winter cycling jacket the Alpha RoS but transforms it into a casual version. Borrowing all the same technology and fabrics the Alpha MC provides the same deep winter protection as its on bike sibling.

The exterior of the jacket is made from GORE-TEX INFINIUM™ WINDSTOPPER® fabric. The lightweight fabric has a unique membrane that delivers the triple crown of being completely windproof, highly breathable, and water repellent, while offering insulation. Minimal seaming and seam sealed shoulders eliminate points where moisture can enter the jacket.

The signature Alpha double-layer construction provides superb insulation with PrimaLoft® synthetic down and a nylon liner that fits over other layers.

Just like Castelli’s on-bike kit, all the details are there. A YKK® Vislon® zip makes for easy opening and closing. A raw-cut edge waist helps create a seal blocking out any wind, as does the new double-layer cuff design. The usual 3 rear pockets are traded for two front pockets as well as an inner chest pocket. A hood completes the jacket so you can be as warm as possible making your way to the start line, or kick starting your recovery.
