Down jacket
A down jacket or puffer jacket is a quilted, padded jacket filled with down feathers. This material is usually used to insulate an Outer layer which is usually some synthetic fiber such as nylon or polyester.History
The first down jacket, then known as an "eiderdown coat", was designed by Australian chemist George Finch for the 1922 Everest expedition and made by SW Silver and Co. It was bright green, composed of hot-air balloon fabric. Finch's jacket was initially mocked by other members of the party, but later won respect for its effectiveness in the windy mountain environment. Since this time many fashion designers have adapted and commercialized the concept of the puffer jacket.
