Each pore is larger than a vapour molecule and they can transpire out through the membrane using temperature differential. That is the difference between the temperature outside the membrane and that inside the membrane. The greater the differential, the more effective the transpiration.
Just a note on pit zips. If you were wearing a breathable jacket and you lowered the temperature inside by opening zips, then you decrease the temperature differential. It may create the perception of cooling the wearer but the breathability will be compromised.

you're letting moisture out with pit zips as well reducing the amount that needs to move through the gore tex....
you can talk all you want about temp differential. i've walked on cold dry days with a rainshell on and even on the flat with plenty of wind, i built up sweat inside, gore tex can't cope with the sweat generated during prolonged exercise...

I am a brolly convert, use it for almost anything other than Winter rain.
I am yet to see anyone else with an umbrella and I do feel like a bit of a tool for having one, however the comfort it brings me outweighs any embarrassment.

I attach it to my pack shoulder straps using some rubber bands that were around a bunch of asparagus previously . . .
