PFAS testing

Product safety is one of our design priorities. We understand many of you are concerned about the PFAS. Not only work with reliable suppliers who have STANDARD 100 by OEKO-TEXยฎ certified materials, but we also did an additional PFAS test on our finished products โ€” fabrics & elastic textiles.
