How the technology works
At Mammut, we're always exploring more sustainable and resourceful practices. When we tested reused rope for insulation, we found that while climbing ropes made from polyamide weren't effective, rope production offcuts made from polyester had fantastic insulating properties – and from this, we developed Mammut LOOPINSULATION.
Industrial rope offcuts undergo a mechanical recycling process. These ropes are untwisted into single rope strands, which are then brushed together and combined with recycled plastic to create polyester sheets or clusters – using no extra chemicals.
These polyester sheets or fiber balls are placed with great care inside our jackets to form synthetic insulation for warmth and protection against cold and wind. The result is next-level insulation with a lower environmental impact.
