A guide to materials,

their impact,

and their sustainability.

The choice of material can determine a big part of a garment’s environmental impact. When choosing materials, traceability and knowledge of the entire production process must be taken into account, from raw material to end of life.

We have created a Material Index where we have divided raw materials into four different categories from “Preferred” to “Banned”.

The Material Index ranking is based on material research and aspects of sustainability from environmental, social and animal welfare perspective.

The Material Index Ranking offered here should be taken as a guide. To measure your actual impact, the actual materials used, its suppliers and supply chain must be taken into account.

We underscore the importance of understanding the complexity of comparing fibers and the need to look at products from a life-cycle perspective, when including the user phase as well as end-of-life.
