Extra warmth for extra cold days. The Women's Rocky Shore 3-in-1 Jacket is an extremely warm parka. Both the outer and inner jackets incorporate warm synthetic insulation. The waterproof Texapore outer jacket has thinner lining, so it can be worn on its own on milder days as a weatherproof shell. All you have to do is separate the two jackets via the System Zip.And the inner jacket is also great to wear on its own as a windproof, very breathable jacket. Zip them together again and they make a really warm winter combo. The hood has a fake fur trim that keeps the wind and cold away from your face. Both the trim and the hood are detachable.
