VERIFY MATERIALS BEFORE YOU INQUIRE
Six published CTI reports cover the listed parts of the tested men's and women's samples.
Current-product production-consistency declaration: Xiamen Xiangying Technology Co., Ltd., Yishuangjia and founder Lin Xiangnan declare that current men's and women's products follow the same material-selection and production-quality standards as the tested samples, and that their main fabric, sewing thread and overlock thread use all-cotton materials. Products purchased by customers are produced to this common standard.
This is a manufacturer and brand declaration, not CTI testing of every item or every production batch. A change in material, supplier, process or style requires renewed verification and an updated disclosure.
These results support transparent comparison for buyers who care about everyday skin-contact comfort and material disclosure. They do not prove the elastic core, other styles or batches, fluorescence, antibacterial or sterile properties, or medical effects.
