The G-LOFT® bi-component-fiber is permeated with a micrometer fine air channel. As a hollow fiber, it ensures as in nature the fur of polar bears, for optimum thermal insulation. The fiber consists of two different materials, which contract to varying degrees during cooling after spinning process.
This creates a spiral shape – like a spring – which is permanently fixed in the molecular structure. Due to the “MEMORY-EFFECT” the G-LOFT® insulation returns always to its particularly warm, airy original shape.
