G-LOFT® is a premium synthetic insulation fibre by Austrian manufacturer Goldeck Textil, which is used in high-end outdoor clothing and equipment. As an innovative high-tech material, G-LOFT® combines the advantages of natural down with the robustness of synthetic fibres: It is extremely light, warm, highly breathable and moisture-regulating, even in wet, cold weather. In addition, G-LOFT® is highly compressible, but it bounces back to its airy original shape, even after bearing a heavy load – for enduring optimal heat insulation.

Martini Sportswear uses G-LOFT® in its spring/summer collections, as well as the autumn/winter collections. Thesustainable G-LOFT® ECO EVOX is used in a variety of Martini jackets and waistcoats from the ECO POWER LINE. It combines high-performance PES (polyester) with unique recycled fibres and offers an outstanding heat-weight ratio. G-LOFT® insulations are among the highest performers on the market and they are 100% made in Europe.  

G-LOFT® is based on a bi-component fibre, which is hollow inside for optimal heart retention – polar bear fur acted as a model. It is made from two different raw materials that form a spiral – comparable to a coiled spring – so the G-LOFT® insulation always bounces back to its original shape. Like down, the G-LOFT® fibres form natural clusters with countless little air pockets that trap body heat and let air circulate optimally. This ensures perfect temperature regulation and excellent heat insulation that can actually match natural down padding.

Thanks to the special technology with spiral-shaped hollow fibres, G-LOFT® insulations boast an impressive heat-weight ratio. That means, G-LOFT® is noticeably lighter and achieves higher loft with more air pockets and a proven higher thermal performance than other insulation materials of the same weight. The fill power of G-LOFT® is comparable to that of duck down.

At the same time, the material can easily be compressed; after unpacking, the soft loft quickly rebuilds, and the fibre structure is retained (“memory effect”).

Other than down, the synthetic fibre doesn’t absorb moisture, so even when wet, it guarantees a high thermal performance. That is why G-LOFT® clothing is optimally suited for use in wet, cold areas.

Thanks to the natural cluster structure of the fibres, air can circulate optimally, which makes clothing highly breathable, moisture-wicking and ensures that the body stays warm and dry, even when you break a sweat.

In addition, G-LOFT® is free of animal materials, making it ethically sound and allergy-friendly. 

G-LOFT® insulation comes in different qualities for a variety of uses. For its outdoor clothing, Martini Sportswear uses only insulation material from the innovative ECO POWER LINE, which combines the excellent properties of G-LOFT® with maximum sustainability.
