Our clothing that are made from only 100% organic cotton are GOTS certified. Where we use a melange of fabrics (such our 70% viscose from bamboo and 30% organic cotton), these are OCS certified. Don’t be fooled though! Most of the benefits of organic cotton and bamboo go away if the dye used contain harmful materials which is why all our fabrics (cotton or otherwise) are certified by OEKO Standard-100 which means the dyes used in our fabrics do not use toxic chemicals or harmful substances.
