A down jacket is a popular insulated outerwear that keeps you warm in cold weather. It is also known as a puffer jacket, quilted jacket, or parka. A puffer jacket is called so because of the puffiness created by the down insulation layer. A quilted jacket features a top layer stitched to a bottom layer, leaving pockets of space for insulation. A parka is a long, thick down jacket designed to protect you from extreme cold weather. Other synonyms for down jackets include bomber jacket, winter coat, ski jacket, and snowboard jacket. Whatever you call it, a down jacket is an essential item for anyone living in cold climates.
