In reply to ben b:
Yeah, physics rules and language sucks... I will have to rephrase my question (which I ask in this forum as Crux is British)
Some single skins are pretty waterproof and breathe poorly, some are merely windproof but breathe better. All suffer from condensation to varying degrees. However, some single skins have an inner surface which absorbs moisture preventing it from dripping down your face. If the temperature and outside humidity is in favor, the moisture will be conveyed to the outside by whatever mechanism the actual fabric supports. If not, it will stay on the inside, but not drip (so much).
ToddTex is a well known fabric, which does exactly this - it is fuzzy on the inside, and it breathes. Now, the X-tex has activated carbon on the inside which should manage moisture in a similar way.
Compared to similar fabrics,
1) How waterproof is X-tex?
2) How well does it breathe?
3) How well does it manage moisture, preventing from dripping?
Thanks
