macteacher,
I think this is fairly common with those membranes, i'm not sure why because the lower humidity outside and the higher humidity inside should drive the moisture out. I have friends who go up north and have issues with goretex freezing because the moisture gets frozen inside the membrane i guess... at -27C you end up with a jacket which has a layer of frost on the back and is stiff as a board... not a good situation. I was looking at mec's whoosh and shower's pass elite... and the largest difference is the whoosh has GIANT pitzips... from your elbow to your mid stomach, which may be a better solutionn for moisture removal if the jacket is frozen.
IF you have cold feet, try removing a layer... making sure you have lots of space, socks aren't too tight(happens if you have too many layers) aren't wearing hard-toe shoes, and most importantly have protected the pulse point on your ankle from the elements with a longer ski-type sock or even an ankle warmer.
I rode that same day for an hour... i only wore a some windproof fleece pants, windproof briefs a thin t-shirt of polypropelyene and a mid-weight merino long sleeve under a windstopper jacket.
Some moisture in your mid-layer is normal, too much is dangerous especially if you feel wet(not just mildly clammy) while riding.. you will get cold very quickly if you have to stop for a repair.
