Cotton is our most widely used fiber. However, the resource-intensive cultivation of conventional cotton has a massive negative impact on the environment and the people involved in the production process.

That's why we switched completely to sustainable* cotton (*Better Cotton or higher certified, for example organic cotton) at the beginning of 2023. 

We have been part of Better Cotton, the world's largest cotton sustainability program, since December 2020. Better Cotton supports cotton communities while working to protect the environment and promote its regeneration. The initiative trains farmers around the world in more sustainable farming practices. In addition, Better Cotton advocates for the rights and welfare of cotton farmers. Better Cotton uses a mass balance system, meaning cotton is combined with conventionally grown cotton in a complex supply chain.

In 2022, we went a step further and had our entire supply chain certified by Control Union for the Organic Content Standard (OCS) and the Recycled Claim Standard (RCS). The seals enable us to record the content and quantity of organic or recycled cotton in a final product and to track the raw material from source to end product.

Linen is obtained from the stems of the flax plant. Flax is quite undemanding and thrives in a wide variety of locations. Today, the largest cultivation areas are in China and the European coastal regions.

Conventional cultivation of linen requires fewer pesticides, mineral fertilizers and less water than cotton cultivation. However, the harvesting process is significantly more laborious. Linen therefore accounts for only about 2% of the world's fiber supply.

Hemp is undemanding and grows in almost any soil - from the tropics to Siberia. In hemp fields there is a very humid climate, actually perfect for fungal attack. However, hemp is very resistant to this and no chemical fungicides are needed. The raw material is optimally utilized, as everything from the seeds to the leaves to the stalks can be utilized. The textile fibers are obtained from the stalks, resulting in a very tear-resistant and stable yarn.

At Mustang, we are committed to protecting animals. Our stated goal: to responsibly and ethically source products that contain animal fibers or substances. Sheep and goats provide wool for our products. They are treated according to the Five Domain Models for animal welfare and raised on farms that contribute to environmental protection. Mustang has been using only mulesing-free wool since as early as 2021. You can find our entire Animal Welfare Policy under "Animal Welfare".

Viscose is a synthetic fiber of natural origin based on cellulose. The basis is mainly eucalyptus, bamboo, pine and beech wood. The viscose process is a complex one that requires a lot of energy - even though the cellulose fibers are of natural origin. Nevertheless, the production is more environmentally friendly than that of conventional cotton or purely synthetic fabrics.  

Like viscose, modal fibers are obtained from 100% cellulose. The difference to viscose lies on the one hand in the spinning process, on the other hand modal consists exclusively of beech wood. Beech wood often falls off during forest maintenance or processing in the wood industry. Modal fabrics are smoother, more absorbent and more robust compared to viscose.

Lyocell is also a further development of viscose. In our collections we mainly use Tencel® Lyocell. Tencel is the brand name under which the Austrian company Lenzing produces Lyocell.  Lenzing only uses wood from sustainably and legally managed forests for its production. In contrast to the extraction of viscose, the spinning process does not use toxic chemicals, but organic solvent. According to Lenzing, its process for producing lyocell fibers saves about one-third of the water otherwise required for viscose.
