Frozen lakes, snow-covered trees and temperatures below freezing - if you want to enjoy the winter countryside to the full, you need proper weather protection. The ROCK ISLAND does the job perfectly. The outer fabric of the parka is our waterproof TEXAPORE FUNCTION 65 - a technical weather protection fabric with a robust, rugged cotton-like finish and superb wear comfort. The inner jacket has a thick layer of recycled MICROGUARD insulation to keep you warm. In the spring, when you only need the shell, or in the autumn, when all you need is the warm inner jacket, you can unfasten the system zip and wear the two garments separately.
