In reply to angry pirate:
Well, as I understand it (from my limited outsider view), there is nothing really that much new about the nano-spinning process (even the "old" Neoshell was probably some variant of it), plenty of research and applications already, I guess the "secret" is in the engineering for large predictable outputs, making the membrane properly hydrophobic and making the hydrophobicity last (which is the main thing keeping "WPB" garments waterproof but breathable, despite most PR nonsense about "size of pores smaller than water droplets") and adjusting the technique to different fabrics.
Still, I am glad they are pushing it (even if at high prices), as it might mean in the long run:
1) more breathable membranes without PFCs
2) hopefully some more affordable ones from cheaper brands with good enough performance by similar process - since it's hardly plausible they hold the patents on the whole of it
Until then, I would have to pass, as the "magic money fairy" seems to have lost my address...
