| GORE-TEX® ePE | The ePE (expanded polyethylene) membrane in the new GORE‑TEX® products is a key step towards responsible performance, delivering highly durable and high-performance products designed for long-lasting use. The brand-new GORE‑TEX® ePE membrane is lightweight, thin, yet strong. To create a GORE-TEX® product, the membrane is combined with carefully selected fabrics, such as recycled fabrics, solution-dyed or undyed***. * Contributes to Gore Textiles’ goal of eliminating environmentally concerning PFCs from the lifecycle of its consumer products. Here, this is achieved through the use of non-fluorinated materials. ** Thanks to the use of a new lower-mass membrane and selected laminate textile(s) (Higg MSI). *** Depending on the laminate used. |
| CORELOFT™ | Developed by Arc’teryx, CoreLoft™ insulation is a synthetic insulation made of fibres of varying sizes that are locked together to trap air and retain heat. This insulation is available in several thicknesses for different levels of performance and comfort. Lightweight and highly compressible, durable and resilient, it retains heat when wet and dries quickly. |
| BLUESIGN® | The bluesign® system is the solution for an environmentally responsible textile industry. It eliminates harmful substances at the start of the manufacturing process and establishes and monitors standards for safe and eco-friendly production. |
