A down jacket, commonly referred to as a "puffer" or "quilted jacket," is a type of outerwear garment designed for cold weather conditions, known for its exceptional insulation properties and lightweight composition. Primarily intended to provide warmth and protect against chilly winds, a down jacket typically has a thick layer of insulating material, called "down," in its interior. Down refers to the soft, fluffy plumage found beneath the feathers of ducks or geese, known for its excellent thermal insulation due to its ability to trap warm air.
The construction of a down jacket involves a series of chambers or pockets filled with down, usually stitched or quilted to prevent shifting or clumping of the insulation. The outer shell is typically made from a durable and water-resistant fabric, such as nylon or polyester, to shield the wearer from moisture or snow. Many down jackets also feature a hood, adjustable cuffs, and a zip or button closure to provide additional protection against cold air and wind.
Down jackets are highly regarded for their remarkable ability to deliver excellent warmth-to-weight ratio, making them a popular choice for outdoor activities like skiing, hiking, or mountaineering. They are also favored as everyday winter wear due to their comfort, packability, and stylish designs. It is important to note that ethical concerns have arisen regarding the sourcing of down materials, and alternative synthetic insulations are available for those who prefer a cruelty-free option.
The word "down jacket" is a compound term derived from the words "down" and "jacket".
The term "down" comes from the Old English word "dūn", meaning "feathers". It refers to the soft, fluffy, and insulating layer of feathers found underneath the tougher exterior feathers of birds such as ducks and geese. The word "down" has remained relatively unchanged in its meaning over time.
The word "jacket" has a more complex etymology. It originated from the Middle French word "jaquet", which referred to a short, close-fitting tunic worn by men during the 15th and 16th centuries. This Middle French term ultimately comes from the Old French word "jaque", which referred to a type of armor worn by foot soldiers.
Over time, the term "jacket" has evolved to describe a variety of close-fitting, typically waist-length garments.
