As of 2024, 90% of their leather comes from top-rated suppliers, with a goal to source exclusively from LWG Gold-rated tanneries by 2025. Additionally, Steel Blue emphasizes sustainability by ensuring all leathers are by-products of the food sector, minimizing waste and promoting ethical practices.
