SLY 's ROICA®EF denim series uses ROICA®EF, an eco-friendly recycled stretch fiber with a supple stretch. ROICA®EF is a sustainable recycled stretch fiber made by Asahi Kasei, which recycles yarn that would normally be discarded, such as leftover yarn or unshipped yarn generated in factories, and turns it into new yarn.
It is made from 58% recycled materials and is the first spandex to receive GRS certification.
GRS Certified: The Global Recycled Standard (GRS) verifies recycled content and tracks it from raw materials to the final product.
