| 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. |
