Animal Welfare

For the protection of animals, MAMMUT strives to exclusively source materials of animal origin from responsible animal husbandry. MAMMUT relies on strict, independent and certified animal welfare standards that offer full traceability all the way back to the farm.

Standards and Partners

The Responsible Down Standard ensures that the down and feathers in our products come from geese and ducks that have been treated well. Any removal of down and feathers from live birds as well as force-feeding is strictly prohibited. The entire supply chain is audited by a professional, third party certification body on a yearly basis. The RDS down can be traced back through the whole supply chain, from the final product to the source.


RE:DOWN stands for recycled down, which is reclaimed from old bedding products and sleeping bags that can’t be resold. The down is collected, sorted, washed and sterilized in an environmentally friendly process. It offers the same performance as virgin down and the quality of the down is tested at every step of the production, according to internationally recognized standards. The whole supply chain and process is Global Recycled Standard certified.


The Responsible Wool Standard is an independent standard, which ensures that wool comes from farms with a progressive approach to managing their land, and from sheep that have been treated responsibly. Through the processing stages, certification ensures that wool from certified farms is properly identified and tracked. The RWS is currently being implemented in the global wool supply chain. MAMMUT is committed to source wool according to the RWS as soon as it becomes available.



An independent, global standard for leather that assures sustainable tanning processes, animal welfare and the traceability of materials does not yet exist. This is why MAMMUT works with carefully selected tanneries that use controlled processes to produce high-quality leather. For nubuck leathers used in our shoes, we prefer to use terracare® leather from Lederfabrik Josef Heinen, the traditional German leather manufacturer. All of our leather suppliers have a Leather Working Group rating of Silver or above.




In order to purposefully continue the successful WE CARE journey and demonstrate strong commitment and leadership for the years to come, MAMMUT has defined broad and ambitious 5-year targets for the design & development period 2018-2023 or the market seasons spring/summer 2020 - spring/summer 2025, respectively.

WHY NOT 100 %?
MAMMUT stands for function, innovation and style. Some suppliers, especially small innovative vanguards and start-ups do not have the manpower and resources to have their typically exemplary operations certified by costly and laborious international standards. We do not want this lack of independent certification to rule out a collaboration with such trailblazers from the start. Thus, we included a small margin for such suppliers in our target setting. Where international standards are missing, we take a very close look at the operations of our partners ourselves.
