If OEKO-TEX® is rigorous, Cradle to Cradle Certified® is relentless. This certification evaluates five categories: material health, product circularity, clean air & climate protection, water & soil management, and social fairness.Products are rated from basic to platinum based on performance across all five.

What earns C2C certification at The Blue Suit? All our Black and Ecru Denim. Every untreated wooden button. Our woven labels, prints, washing processes, laser treatments—even our Italian manufacturing facility itself. The only exception: jacket sleeve linings, which are GOTS certified Cupro instead.

Why isn't everything C2C certified? Because the process is expensive and time-consuming. But here's the thing: both C2C and OEKO-TEX® guarantee toxic-free production. The difference is that C2C goes further, addressing circularity and environmental impact across the product's entire lifecycle.
