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?
