The Women's Viking Sky 3-in-1 Jacket is a warm combination designed for ambitious winter hiking trips. The outer jacket is made from very hard wearing Texapore fabric; it will keep you dry and warm even in heavy rain, snow or wind. And the good breathability performance promotes optimal wear comfort.Heat retention is provided in the form of an inner jacket with synthetic insulation. It features a windproof Stormlock outer fabric, which means it's great to wear on its own when rain protection is not required. If you undo the System Zip, the two jackets can be separated and worn individually.
