A down jacket is a warm winter coat. Many people call it a puffer jacket.

These jackets use soft feathers from ducks or geese. The feathers create many tiny air pockets. These pockets trap warm air around your body. This keeps you very warm in the cold. It is a very useful tool for winter.

People measure how fluffy the feathers are using fill power. This number shows how many cubic inches one ounce of down fills. For example, one ounce of 700 fill-power down fills 700 cubic inches. Higher fill power means the jacket is lighter and warmer. It also means the jacket can compress into a smaller size. This is why hikers and backpackers love them.

Water can be a hard job for down feathers. If the feathers get wet, they lose their fluff. This is called losing loft. When they lose loft, they also lose warmth. Some jackets use a coating called DWR to stay dry. This helps them last through a light drizzle for an hour. Some even use hydrophobic down to stop water from soaking in.

These jackets have a very interesting history. An Australian chemist named George Finch wore one in 1922. In 1936, Eddie Bauer made a jacket after a dangerous fishing trip. He sold his design as the "skyliner" in 1939. A designer named Charles James made a fancy satin version in 1937. He called his special design the "pneumatic jacket."

Fashion trends for puffers change all the time. In the 1970s, Norma Kamali made a "sleeping bag jacket." People in Italy wore bright neon colors in the 1980s. During the 1990s, ravers and hip-hop artists wore them often. Today, some people like long coats in beige colors. However, short cropped puffers are still in fashion in 2024.
