Our ECONYL® fabric is created from regenerated ocean plastic, such as abandoned fishing nets and industrial plastic. Not only does this help to remove waste from the oceans, but it also reduces the amount of new materials produced. Our recycled fabric reduces the global warming impact of nylon by up to 90% compared with the material from oil.
