In reply to tony:
It was used in some Mammut pants, amongst other things. I have a pair of Mammut Castor pants that use it and I think it's very good.
It had a thin, almost painted-on membrane type thing on the inside of the material, unlike regular Schoeller. This is not the best for next-2-skin so a mesh lining is often used. But they are great pants - very windproof, stretchy and very water resistant. A tad warm for summer even though they have no insulation, they're just less breathable than regular Schoeller.
