Thought the thread would be interested in this, Gore-Tex has recently released a pretty interesting new textile, bizarrely called Gore Active but completely unlike the previous Gore active products. What makes this product interesting is that is completely skips the face fabric and exposes the membrane as the outer surface while bonding a woven backer on the inside like a conventional 3L product. The result is a fabric that is not only ultralight and waterproof but completely hydrophobic and doesn't rely on DWR. It can't get wet and it doesn't wear away like DWR. Essentially, you can come out a rain storm, shake your coat off and it's bone dry. Unfortunately, it's pretty fragile and and thus best suited as an emergency shell or for very specific end uses. Arc'teryx is using it on a running specific jacket as is The North Face.
Pretty interesting potential applications for this textile though, imagine something like an Acronym WS-J25 but half the size packed down and waterproof.
