Down jeackets are outdoorjackets that feature a quilted look and are generally filled with down feathers or synthetic insulating materials. Down jackets provide excellent thermal insulation on a wide range of cold temperatures. The quilted design of down jackets helps keep the insulating material evenly distributed along all parts inside the jacket.
