With new ePE Gore-Tex making its way onto the market, we're highlighting the key similarities and differences between this new waterproof membrane, and older versions of ePTFE Gore-Tex.
In summary, the similarities are exactly where you want them to be, in the performance of the membrane. However, key differences come with the care of your ePE garments. This care is essential to the performance, so we've also written a guide to help you out with that.
This new membrane uses a thin, microporous layer; each square inch of a GORE‑TEX membrane contains nine billion pores, each small enough to block rain and wind, yet large enough to let sweat vapour escape. The result: reliable waterproof, windproof, and breathable protection, even during high-output activities.
Eco Upgrade
Older Gore-Tex relied on ePTFE membranes and DWR coatings containing persistent “forever chemicals.”ePE is a fluoropolymer-free material and is paired with PFAS-free water-repellent finishes, helping Gore reduce its carbon footprint while minimising harmful chemistry. You get the same trusted performance, with a lighter impact on the planet.
Washing Your Gore-Tex ePE Jacket
How Often to Wash
Unlike older Gore-Tex jackets with long-lasting DWR, ePE jackets benefit from more frequent washing to maintain performance. You don’t need to wash after every trip, but don’t let the jacket stay dirty.
Wash and re-proof whenever water stops beading on the surface (a sign the DWR is wearing down), or after exposure to heavy dirt, mud, salt, or oils. Regular cleaning, performed a few times per season or several times a year, depending on your usage frequency, helps the jacket breathe and repel water effectively.
