Returns information
Lightweight, breathable, and reliable even when wet, Mammut LOOPINSULATION jackets are built with 100% recycled insulation from industrial rope production offcuts and recycled PET. Made to keep warmth close through shifting temperatures.
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.
