: I believe that water vapor molecules are smaller than their liquid
: counterpart. That's the reason Goretex works. Vaper gets out, water cannot
: get in.

: Ted

As I recall from high school chemistry:

H2O is H2O. The basic charges between the atoms remain the same. What is different is the energy of water vapour/water/ice. Adding energy to ice turns it into water and more energy turns it into vapour. By adding energy the molecules move faster and their separation increases. I suspect Gortex works because vapour on the inside of the garment has more energy, the molecules are further apart and can pass through the membrane individually. Water on the outside of the garment has an affinity to "cling" to each other thus preventing passage through the fine weave of Gortex.
