Mammut LOOPINSULATION

An outdoor adventurer in a blue Mammut jacket relaxes on a tree branch beneath a bright, partly cloudy sky.

Process

  • Collecting rope offcuts

    Polyester-based rope offcuts from industrial rope production are gathered – materials that would otherwise be discarded.

    Tangled colorful Mammut climbing ropes in various patterns and colors against a light background.
  • Transforming materials

    These offcuts are then untangled into single strands which are brushed together and combined with recycled plastic.

    Hands crafting a blue Mammut mountaineering jacket, featuring fabric and stuffing, with scissors and a ruler in the background.
  • Creating insulation

    The end result is fluffy polyester sheet padding and cluster fill, which creates warming insulation for our jackets.

Our next-level insulated jackets – made with Mammut LOOPINSULATION, a high-performing synthetic fill – are light enough to stash away on the uphill and warm and protective for when you’re enjoying the view or scrambling on the way down. You’ll feel cocooned in your own cozy space. It’s the ultimate breakfast-in-bed feeling: protected, comfortable, and completely at home with no walls and no roof needed.
