Introducing Patagonia's Innovative GORE-TEX ePE Rainwear

Technology company GORE TEX, and outdoor apparel company Patagonia have been on a mission to create top-tier, per- or polyfluorinated chemicals (PFC) free waterproof kit tailored to keep people warm and dry even in the wettest environments. The result: Patagonia are using New GORE-TEX fabrics with ePE membrane or Expanded Polyethylene – a revolutionary material setting a new standard of durable, waterproof, windproof and breathable protection.

In the past, waterproof fabrics were coated with heavy oils and waxes, requiring frequent reapplication. This led to the development of waterproof membranes. These fine films, bonded to the back of the exterior shell, feature tiny pores that block water infiltration while allowing sweat to evaporate. The challenge was to make these membranes durable without compromising on performance. This is where GORE-TEX product technology comes in.   

Expanded polyethylene (ePE) is a strong yet lightweight material that makes kit durable and waterproof without using perfluorinated chemicals. Traditionally, expanded polytetrafluoroethylene (ePTFE) was used for these membranes due to its exceptional hydrophobic and durable qualities. However, ePTFE production involved PFCs and PFAS, which are known for their environmental and health risks. GORE-TEX ePE is made without these chemicals, offering a responsible alternative without compromising performance.
