Down is an animal byproduct that can be sourced sustainably and ethically. Responsibly sourced down is harvested without causing undue harm. While there is a history of unethical treatment within the down industry, including live-plucking and force-feeding, there has been closer scrutiny that has led companies to seek out ethical suppliers. Shoppers can look for certain certifications, such as the Responsible Down Standard, that indicate a traceable supply chain and humane treatment of the ducks and geese from which the down is sourced.
