Throw out everything you know about cycling jackets cause the Castelli Alpha RoS Jacket takes it to another level. It keeps everything that made the original Alpha jacket so great, the two layer construction to separate the insulation layer from the outer shell, the double front opening to diffuse the cold air when you open up to ventilate, the excellent breathability, the flat wrist and waist openings, the articulated collar, the insanely soft stretch fabrics, and the great fit. The Castelli Alpha RoS Jacket utilizes GORE-TEX INFINIUM rain resistant membrane and DWR treatment, selective seam sealing, careful seam placement and construction, and a waterproof YKK Vislon zipper, essentially making it waterproof while not compromising the characteristics that make it such a great dry weather jacket. In short, It’s a game change.
Rain or Shine engineering provides insulation and breathability for cold and dry rides, with effective waterproofing for wet rides
GORE TEX INFINIUM 150 fabric provides wind protection with high breathability and effective rain protection
Seam sealing on shoulders, reduced seaming and double stitching helps keep you mostly dry
Alpha construction separates wind/water protection layer from insulating layer
extra pocket with waterproof zip for your most valuable riding essentials
