Be all end all of Gore-Tex
I can't find the thread where we were arguing over synthetic vs. wool... anyways, here's the official Gore-Tex reponse:

Hello Mitchell,
Thanks for your interest and inquiry about GORE-TEX® products.
The GORE-TEX® membrane is extremely stable and is able to withstand extreme temperatures from -250oC to +260oC. Many highly experienced adventurers use only GORE-TEX® garments in extreme conditions. Your body heats the air trapped in the layers beneath your outer or shell layer, this is called the micro climate, which creates a significant difference between the moisture vapour concentration on either side of the fabric, which is called the driving force. This driving force ensures that all moisture is drawn to the outside of the garment. One of our directors recently undertook a trek to the North Pole and said his GORE-TEX® garments worked extremely well under adverse conditions.
GORE-TEX® Australia also sponsor Australia's most accomplished high altitude mountaineer, Andrew Lock, who relys on his GORE-TEX® garments for survival and often has to spend many days in sub zero temperatures. He has just completed his thirteenth summit of the worlds 14 mountains over 8000 metres. See his web site here,

We also sponsor two young adventurers who have crossed, unsupported, Victoria Island in the Arctic and they swear by their GORE-TEX® equipment. See their web site here,

So, GORE-TEX® does not have the breathability affected by low temperatures.Use it with confidence.
Best regards
Phil Askew
