Exhale a warm breathe into a ziplock bag and you can get a pretty good visual of what's going on inside that jacket.
As others have said, your body is creating a warm, moist environment while outside of the jacket is a cool, wet environment. There just isn't enough difference for osmosis across the membrane.
Breathable rain jackets also work better the closer you can get them to your skin. FYI
