The weather might not be terrible now, but rest assured, it's going to get painfully cold in the next few weeks. When winter truly gets harsh, there is nothing that will keep you warmer than a down jacket. If you want to get technical about it, down jackets use the heat retentive qualities that feathers provide to keep all natural warmth in, and the frigid air out. In other words, you'll be toasty as fuck. From luxe versions from Moncler, to affordable and functional from Uniqlo, these are The Best Down Jackets To Buy Now.
