Materials are a central component of our products.

On this page, we provide insight into the types of fibers we use at Mustang, show in which areas we use certified or comparatively more responsible fiber alternatives, and explain the goals we have set for selected materials. We differentiate between natural fibers and synthetic fibers in textiles. Natural fibers consist of raw materials found in nature; synthetic fibers can be of natural or non-natural origin. In selected areas, we are working to increase the share of organically certified, recycled or alternatively sourced materials. This development takes place step by step and refers specifically to the material groups and targets mentioned. The statements on this page each refer to the specifically mentioned materials, programs or objectives.

Natural fibers

Natural fibers are renewable raw materials obtained from plants or animals that are processed directly without synthetic processes.

Cotton

Cotton is the fiber we use most frequently. According to our data, we use cotton for around 90% of our total annual fiber volume.

However, the resource-intensive cultivation of conventional cotton can have a massive negative impact on the environment and the people involved in the production process.
That’s why our sourcing strategy consists of sourcing BCI Cotton under the mass balance Chain of Custody, and certified cotton since 2023. In 2025, we sourced 80,9% of our cotton as BCI Cotton.

We became a member of the Better Cotton Initiative (BCI™) in December 2020. BCI is the world`s largest cotton sustainability program, whose mission is to help cotton communities survive and thrive while protecting and restoring the environment. BCI advocates for the rights and well-being of cotton farmers around the world and promotes better standards in cotton farming practices. BCI uses a chain of custody model called mass balance, which cannot be physically traced back to the final product. However BCI farmers benefit from the demand for BCI Cotton in a quantity to that which we ‘source‘.

Since October 2022 we are certified to the Organic Content Standard (OCS) and the Recycled Claim Standard (RCS), Control Union (1138780). Products certified to the Organic Content Standard (OCS) contain organically grown material (such as cotton) that has been (independently) verified at each stage of the supply chain, from source to final product. Products certified to the Recycled Claim Standard (RCS) contain recycled material (such as cotton) that has been (independently) verified at each stage of the supply chain, from the recycler to the final product. Only the products which carry the Organic Content Standard (OCS) or the Recycled Claim Standard (RCS) label and claim are certified. Our certified products are identified by a label on the hangtag.

Animal fibers

We aim to use as few animal fibers as possible at Mustang. According to our data, animal fibers account for only around 1% of our total annual fiber volume.

We are certified to the Responsible Wool Standard (RWS), the Responsible Mohair Standard (RMS) and the Responsible Alpaca Standard (RAS). The RWS verifies wool, the RMS verifies mohair and the RAS verifies alpaca fiber animal welfare and land management requirements and tracks it from farm to final product. Only the products which carry the Responsible Wool Standard (RWS), the Responsible Mohair Standard (RMS) or the Responsible Alpaca Standard (RAS) label and claim are certified. Our certified products are identified by a label on the hangtag.

Starting in early 2024, our procurement strategy calls for sourcing only certified animal fibers.

In addition, we have defined further requirements for animal welfare at Mustang in our animal welfare policy: Animal Welfare Policy

Man-made fibers

Man-made fibers include all fibers that are produced industrially or chemically. Depending on the raw material, they are divided into two subgroups: synthetic fibers, which consist of synthetic polymers (e.g. polyester, polyamide, elastane), and regenerated fibers, which consist of natural polymers (cellulose) and are chemically processed (e.g. lyocell, viscose, modal, cupro)

We are certified to the Recycled Claim Standard (RCS).
Products certified to the Recycled Claim Standard (RCS) contain recycled material that has been (independently) verified at each stage of the supply chain, from the recycler to the final product.
Only the products which carry the Recycled Claim Standard (RCS) label and claim are certified. Our RCS certified products are identified by a RCS-label on the hangtag.

Starting in 2025, our procurement goal is to use as few man-made fibers as possible and to source at least 50% of our man-made fibers as certified fibers or fibers from the Lenzing brand.

Textile fibers

Textile fibers can be divided into two groups:

Natural fibers

Synthetic fibers

Measured in terms of our total fiber volume, we use natural fibers in around 90% of our product.
Natural fibers include plant fibers and animal fibers. They consist of naturally occurring, renewable raw materials.

Since 2023, we have switched completely to more sustainable cotton (Better Cotton or higher certified).

Cotton

plant based

Linen

Hemp

Wool

Measured against our total fiber volume, we use synthetic fibers in around 10% of our products.
In the case of synthetic fibers, a distinction is made between those of natural origin (from naturally occurring, renewable raw materials, e.g. wood) and synthetic origin (from non-renewable raw materials, e.g. petroleum).

From 2025, we aim to use more than 50% synthetic fibers of natural origin or synthetic origin recycled.

We want you to be able to make a conscious decision. That's why we already inform you about the sustainability features of your product directly on the hangtag. You will also find this information on the Care Label and in our online store.

Animal welfare

Animal welfare and a species-appropriate treatment of animals are particularly close to our hearts.That is why we only use very selected animal fibers. The use of leather and animal hair in our products has undergone a lasting change.

Our Animal Welfare Policy defines which animal fibers maybe used in our products. Specifically, this means that we do not use noble hairs such as angora and cashmere.Since the Autumn/Winter 2024 collection, all of our alpaca fibers are certified to the Responsible Alpaca Standard (RAS) and all of our mohair is certified to the Responsible Mohair Standard (RMS), Control Union (1138780). Products certified to the Responsible Alpaca Standard or the Responsible Mohair Standard contain alpaca fiber or mohair from farms certified to animal welfare and land management requirements. Both standards ensure the traceability of the fibers from the source to final product. Only products which carry the RAS label and claim or the RMS label and claim are certified. Our RAS and RMS certified products can be identified by the RAS or RMS label on the hang tag. We completely avoid fur, down, silk or exotic skins and only use leather when it is a byproduct of the food industry.

We actively support initiatives such as the Four Paws campaign against mulesing to improve animal welfare. This method involves cutting skin from lambs without anesthesia. A procedure that we strictly reject. Our promise: in our products you will find only 100% mulesing-free wool. Additionally, since August 2022, we are certified to the Responsible Wool Standard (RWS), Control Union (1138780). The Responsible Wool Standard describes and certifies animal welfare and land management practices in wool production and tracks the certified material from farm to final product. Only products which carry the RWS label and claim are certified. Our RWS certified products can be identified by the RWS label on the hang tag.
