For warmth and comfort in sub-zero conditions, this thermal vest is insulated with a specialized synthetic fill: our one-of-a-kind Mammut LOOPINSULATION, made of recycled rope scraps. Combined with a recycled wind- and water-repellent outer fabric, this cozy layer offers the protection you need and marks an important step towards achieving a more circular economy, and responsible production with the lowest possible impact on the environment.

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

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

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.
