UK exclusive colourway for the Castelli Alpha RoS Light Jacket which uses the same philosophy as its big brother but by using lighter weight fabrics and less insulation its aimed at warmer winter conditions.
Created as a replacement to the original Alpha jersey it features Gore Windstopper 150 fabric on the front and sleeves to greatly increase its water repellency especially with the addition of selective seam-sealing where required to further enhance its resistance to rain.
The back is in woven Nano Flex Xtra Dry that offers exceptional waterproofing but with greater breathability when compared to a membrane.
The Alpha Light Jacket retains the chest insulation with a separate zipper that's used in the heavier jacket allowing you to customise your insulation/ airflow priorities. Also of note are new waterproof zippers, pocket drainage similar to the Gabba jersey and cross wrap over under wrist closures.
All this to create a garment that is comfortable in a wide range of temperatures and conditions, it might not keep every drop of rain out but it will leave you comfortable, warm and dry but never sweaty - more so than any other garment.
