Our Future Programme

Sustainable materials

More sustainable from beginning to end

A more sustainable product starts with the design and the choice of materials. We’re still not perfect, but we have a clear goal in sight: to broaden our portfolio of more responsible materials even further. In doing so, we reduce the risks to people and the environment.


Cotton is one of our most important raw materials. To promote socially and ecologically produced fibres, we use verified sustainable cotton from the Better Cotton Initiative or Cotton Made in Africa, as well as certified organic and recycled cotton. Through our Empowering Farmers project, we support farmers in the cultivation of organic cotton in India, in addition to the purchase of sustainable materials.

Materials of animal origin

We only obtain materials of animal origin from responsible sources. This is how we protect the welfare of animals. That’s why we work with certified materials of animal origin, for example from the Good Cashmere Standard or the Leather Working Group. For selected product groups where materials of animal origin such as leather have been used up to now, we are trying to continuously increase the proportion of vegan alternatives.

For more information on the cotton we use and how it’s certified:

Cellulose fibres

Cellulose fibres include viscose, modal or lyocell, for example. They are made from renewable raw materials, especially wood. We rely on the more sustainable branded fibres of BIRLA CELLULOSE™ from LENZING™.

Synthetic fibres

We are working on using as little new polyester in our products as possible. By using recycled polyester, we are keeping the fibres in the material cycle for longer and no new resources are used. The recycled polyester comes from PET bottles or old clothing, for example. Overall, we are working to reduce the use of synthetic materials.

What we are going to do next

In our strategy for more sustainable materials, we have continuously been setting ourselves targets for the use of even more sustainable materials in all our products for several years now. And we’ll continue to work on it in the future – for even better styles!
