| GORE-TEX ePE | The ePE (expanded polyethylene) membrane in new GORE-TEX products is a key step on the road to responsible performance, providing high performance, durable products engineered for long life. The all-new GORE-TEX ePE membrane is light, thin but strong. To form a GORE-TEX product, the membrane is combined with carefully selected fabrics, such as recycled, solution-dyed or undyed*** fabrics. *Contributing to Gore Textiles' goal of eliminating PFCs of environmental concern from the life cycle of its consumer products. Here, the objective is achieved by using non-fluorinated materials. ** Thanks to the use of a new membrane with a lower mass and the textile(s) selected for the laminates (Higg MSI). *** Depending on the laminate used. |
| GORE® C-KNIT™ | Garments made with C-KNIT™ lining technology have the strength of a 3-layer laminate combined with a superior level of softness and fit. Its unique and patented laminate construction features a precision mesh with a circular structure, which is very pleasant to wear. This material slips easily over other layers of clothing, whether they're base-layers or mid-layers. Garments made with this lining technology are extremely breathable. The lightness of the material and the airy construction of the lining, combined with a special lamination process, allow perspiration to pass through and escape more easily. |
