Hybrid fabrics?

There was a custom order fabric that was offered on BPL a couple years ago.  It was a sandwich with nylon, and a thin layer, not of polyethylene, but one of the waterproofing layers used in Dyneema sandwiches.  Unfortunately, some tests by a BPL fabric guru revealed issues developing with delamination.  A shame, because the hand of the fabric was more like nylon, and much softer than the D-P laminates, like X-Pac, that backpackers often use.  I think the coatings coming out recently are so good, that there is no need to experiment with the clear materials used by D-P for waterproofing.  https://backpackinglight.com/forums/topic/hh-test-of-extremtextil-20d-silnylon/
