Waterproof breathable "coatings" are useless.


If you're talking about the DWR coating that's placed on Gore-tex
outerwear, you're wrong.




I'm not wrong.

From "REI expert advice".


Water-Repellent Coatings

To maximize water-resistance and breathability, Gore-Tex outerwear comes
with a DWR (durable water repellent) treatment on its outer surface. This
DWR causes water to bead up and roll off the garment, which keeps the fabric
surface clear so that sweat and body heat can pass through from the inside.
DWR treatments also keep the fabric surface drier, which cuts down on
evaporative heat loss and keeps your outerwear light and comfortable.

Over time, with regular laundering and exposure to the elements, DWR
treatments can wear off. When this occurs, water may no longer bead on the
surface of the outerwear fabric, and the fabric may absorb some water (NOTE:
the Gore-Tex barrier beneath the outer fabric will still stop this moisture
from getting to your skin). The best way to renew your DWR is to launder
your Gore-Tex outerwear according to the care instructions and iron it using
a warm steam setting. This will restore the water beading on the outer
surface of the fabric as long as the original water-repellent treatment is
present.

Unfortunately, there is no permanent water-repellent treatment available.
Eventually, after extended wear and/or many washings, the original repellent
finish will be depleted and you'll need to use a spray-on or wash-in
water-repellency treatment to treat the outer surface of the fabric. You may
repeat this process as many times as needed.


If all you have on an item of clothing is a sprayed on coating
and no membrane and they *claim* it's waterproof
breathable, basically what you have is nothing at all, and
they're lying.
