A cool, calm autumn day is the perfect time for a run in the woods and the Mens Skyland Hooded Jacket from Jack Wolfskin will keep you warm while you're doing it. This highly functional stretch fleece jacket was made for demanding outdoor sports. You head straight up the hill and then zigzag down the narrow path to the bottom. It gives you complete freedom of movement. The full-stretch fleece fabric takes care of that. The fabric is extra breathable, too, which means it's ideal for high-output sports. The jacket has flatlocked seams, so you can carry your hydration pack in total comfort with no uncomfortable pressure points under the straps.
