Common logic would dictate that a windbreaker should be left back in the spring, but they're a perfect top layer for wearing heavy knits in the fall. What they lack in warmth, they make up for in being steezy and—like their name suggests—blocking the wind. Chunky sweaters will make you feel warm and toasty and can be worn deep into fall just a windbreaker over them. You can even place a fleece jacket underneath a windbreaker and have enough room to breathe. Plus, when windbreakers are zipped up, they do a decent job of retaining your body heat.
