Materials

Most of the material we use is polyester. Virgin polyester is made from petroleum, which has significant environmental impacts. Recycled materials, such as recycled polyester, enable waste materials such as used plastic bottles, to be utilized in the production of new materials while reducing the need for virgin raw materials. We have systematically increased the share of recycled materials in our products without compromising quality, technical performance, or durability. A detailed material breakdown can be found in our annual sustainability summary. 

Traceability is a key development area and priority for us. When we know the origin and journey of our materials, we can improve supply chain transparency and more reliably assess the environmental impacts of production. We are currently developing Digital Product Passport which will help us to provide more transparent product information and improve product traceability. Our goal is to introduce Digital Product Passport in 2027. 

We require our suppliers to follow best practices that consider animal welfare and do not expose animals to harmful processes. The down and feathers used in our down products are either recycled or sourced as by-products of the food industry. In selected apparel products we have used Untuvia® recycled down. Untuvia’s proprietary, waterless and toxic-free recycling method enables high-quality recycled down. 

The wool we use is mulesing-free. We use leather only in selected footwear products. The leather we use comes from certified manufacturers that follow strict environmental requirements in leather processing. We do not use real fur in our products. 

Halti is a bluesign System Partner. By following the bluesign Criteria, we work to reduce the impact of our production processes, from the chemicals we use to the resources we consume, as part of a more responsible approach to making our products. Bluesign is an independent system that helps the textile industry reduce its impact on people and the planet by addressing chemicals, resources, and processes at the source of production. Selected styles in our collection are made with bluepass certified materials. Bluepass certified materials are produced through processes that meet bluesign Criteria. 

In 2024, bluepass certified materials accounted for 50% of our total fabric purchasing volume, and in 2025 we increased this share to 57%. Our goal is to further increase the use of bluepass certified materials, and progress can be followed in our annual sustainability summary. We comply with the REACH chemical regulation issued by the EU and follow the SVHC candidate list of substances of very high concern to stay up to date with the regulations. We require our suppliers to comply with bluesign Restricted Substances List which provides consumer safety limits and recommended testing methods for the restricted substances in apparel and footwear products.  

Many of our outdoor garments feature a durable water repellent (DWR) treatment that provides water and dirt repellency. We prohibited the use of per- and polyfluoroalkyl substances (PFAS) in our materials in 2020 and require our subcontractors and material suppliers to adhere to this policy through our supplier agreements. 

Traditional DWR treatments have often contained PFAS chemicals, which are persistent substances that can harm the environment and accumulate in the human body. We cannot guarantee with complete certainty that our products are entirely free from PFAS, as cross-contamination may occur during or after manufacturing. 

Many of our outdoor garments use the branded Rudolf BIONIC-FINISH® water- and dirt-repellent treatment.
