A Brief History of Sleeping Bags

The first sleeping bag was created in the mid-1800s. It consisted of a bed sheet sewn into a large bag. Then, during World War II, military members were issued down sleeping bags. Later, in the 1960s, consumers could purchase down sleeping bags for outdoor and camping expeditions.

What is Down?

Before understanding how down sleeping bags work, it is essential to understand what down is and its characteristics.

Defining Down

Down is a natural insulator that grows under the outer layer of waterfowl, like ducks or geese.

The Characteristics and Properties of Down
