Mammut revolutionizes mountain insulation with down innovations and its latest European-produced “Mammut Loopinsulation,” made using upcycled rope scraps.

As we gear up for the upcoming winter season, Mammut is proud to unveil its revamped insulation line in the clothing sector—the all-new Mammut Mountain Insulation, tailored for a wide range of outdoor activities and weather conditions. The company’s primary focus is clearly on enhancing resource efficiency, and durability while embracing circularity. A major milestone in this endeavor is the introduction of Mammut Loopinsulation, now proudly produced in Europe. This innovative, polyester-based insulation material is the result of a collaboration with rope manufacturer Teufelberger and is derived from production scraps originating from the manufacture of industrial ropes. What sets it apart is its unique sheet and cluster technology, which minimizes micro-losses at the same time, does not require any glues at all, and is available in various grammages. “With Mammut Loopinsulation, we are embarking on a journey to reuse our materials with a circular and resourceful approach. This marks the first generation, laying the foundation for the future,” said Helena Theba Material Management Lead at Mammut.

Natural warmth amplified

For over five decades, the Swiss mountain sports outfitter has been using recycled down. The reason for this is more relevant than ever: Fewer natural resources are needed, less waste is generated and in terms of animal welfare, it reduces the demand for new down and feathers from living birds. Today Mammut proudly offers high-quality recycled RE DOWN that complies with the Responsible Down Standard. In addition to these recycled down offerings, Mammut is introducing DRY DOWN technology for the first time next winter. This innovation leverages the natural properties of down while enhancing them. This is achieved by treating the natural insulation material with a PFC-free DWR making it exceptionally moisture-repellent– 90% less water is absorbed–while ensuring that the loft is retained and the wearer stays warm even when damp. At the same time, it dries 30% faster than untreated down.
