Sustainability Score

72%
While Thinx demonstrates commitment to sustainability through their reusable products and OEKO-TEX certification, they face challenges with transparency in their supply chain. The company has made improvements following past labor practice controversies and has implemented better chemical management, but still lacks comprehensive public reporting on their environmental impact. Their B Corp certification shows commitment to ethical practices, though there's room for improvement in supply chain transparency and environmental reporting.
