    From my understanding, there are essentially two kinds of Pertex Shield: one is a dwr-like coating of microporous PU with a hydrophilic PU layer on top. This has a terrible MTVR of around 8000.

    The other Pertex Shield, which I've yet to see, is more like 3-layer goretex, but a hydrophilic PU laminate.

    Does the Pertex Shield coating really stop the breathability of Pertex fabrics? Is Shield on all Pertex Fabrics?

    The reason I ask is because some retailers show the Montane Extreme as Pertex 6 with Shield.

    Also, what is the difference between Shield and Endurance?

    Peter,
    my guess is that the Shield mentioned in combination with Pertex 6 refers to the old Pertex Shield which was supposed to be a DWR-treatment. After Perseverance Mills, owner of the Pertex-brand, went bankrupt, the Shield project was killed. The new owner of the Pertex brand, Mitsui, has revived the Shield name for a new waterproof breathable product which has nothing to do anymore with the previous DWR-treatment.
