Down feathers are prevalent in everyday products such as jackets, sleeping bags and pillows. Goose down is preferred over duck because of its higher fill power and warmth. However, high quality and less expensive duck down can have a similar fill power and properties. Using DNA sequencing, we wanted to investigate down feather samples from a well-known company to see if duck was being used as a substitute for goose.
