Mammut LOOPINSULATION

Process
Collecting rope offcuts
Polyester-based rope offcuts from industrial rope production are gathered – materials that would otherwise be discarded.
Transforming materials
These offcuts are then untangled into single strands which are brushed together and combined with recycled plastic.
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.
