Castelli Alpha ROS 2 Light Jacket

Dress for the conditions and every ride will be more comfortable and more enjoyable. This Castelli Alpha ROS 2 Light Jacket excels as the mercury drops towards single digits, whether it's wet or dry.

Key to the performance of this jacket is the Alpha double-layer construction. A Gore-Tex Infinium™ Windstopper® 150 fabric has been utilised on the front and sleeves and this outer layer can be opened without compromising the inner insulation layer of ProSecco Strada material. Moisture is effectively moved to the outer surface where it evaporates fast, keeping you comfortable and dry. To the back of the jacket is Nano Flex Xtra Dry with a nanotechnology water-repellent finish for both good ventilation and protection from rain and road spray.

The double YKK® Vislon® front zippers mean you can unzip from the top or the bottom, and the jacket is completed with four pockets, one zipped, and with reflective details on the rear pockets for added visibility in low light.
