Before I bought the Super Mica I called Marmot several times to talk about the Membrain coating and the fabric they use to compare it to my Precip and other W/B fabrics.
They told me it does have a DWR coating and that it is supposed to be better than the Precip. The DWR keeps the outer fabric from wetting out, which keeps the fabric breathable. If the outer fabric wets out, the fabric is still water proof, but the surface tension of the water on the surface of the membrane keeps the fabric from breathing.
I was concerned because there were many reports online of the fabric wetting out. Both Marmot and Backcountry.com told me if it does wet out, "wash it with powered detergent, dry it in a hot dryer and it will restore the DWR coating" and "If it still wets out, just give them a call and they will make it right."
So far, a couple of years later it is still working fine. I have washed it twice I think, not because of a wetting out problem, just because it was getting a little ripe
