Down has been used for centuries as an insulation for garments and bedding where maximum warmth was required. Even then, down has always been a by-product from animals used for food. And in all this time nothing has been developed that comes close to the warmth or sustainability of down. It also has the unique ability to retain its loft and performance for many, many years. In many ways, down is the antithesis of the plastic fast fashion so prevalent in the marketplace today.
