In the year 2000, the ETERNA brand was the first manufacturer in the world of men’s shirts and women’s blouses to be awarded the highest OEKO-TEX® 100 plus level certification. This corresponds to the current MADE IN GREEN by OEKO-TEX® label. For this certification, OEKO-TEX® monitors environmental and social aspects (e.g. fair production and working conditions) along the entire supply chain. Our entire value chain has been transparent since 2015 by entering an EAN code online.
