On mountain peaks, coastal trails and forests tracks, the Womens Pacific Sky Jacket from Jack Wolfskin keeps the cold and wind at bay when you're hiking in chilly autumn conditions. While you enjoy the clear, crisp air, the extra warm fleece keeps you warm and comfortable. The extra long, thin fibres on the inside provide superb insulation and have a lovely, soft feel. The exterior is as smooth as a regular sweatshirt. When the wind is howling round your ears, the windproof hood protects your head and stops you getting cold. Both the hood and the shoulders of the jacket have extra insulation.
