Sustainability Score

45%
FNX Fit shows limited transparency regarding their sustainability practices and supply chain. While they use some eco-friendly materials, they lack clear environmental policies and published ESG goals. Their labor practices and factory conditions are not well documented, and they provide minimal information about their animal welfare standards. The brand has made some initial steps toward sustainability but needs significant improvement in transparency and concrete environmental commitments.
