In reply to Tom Ripley Mountain Guide:
I'll ask!
What actually makes you think that though? I know GE are willing to license eVent to firms to sell under their own brand names, BUT eVent was available when Jottnar started making gear, and they said when they started that NeoShell was the only membrane that they thought was good enough, so I guess Sjkoldr has to an improvement on that.
And I am right aren't I that GE make eVent? Because Jottnar's site says their fabric was developed with a Japanese company, so that also argues against it being eVent.
