My first goretex jacket was 40 years ago, they have come a long long way.
With a proper baselayer, I do not get wet inside Gore Shakedry UNLESS I am climbing slowly on a long climb but let's be honest, we'd be sweating in our birthday suit on an extended climb.
I was backpacking in the Smokes this spring and it was pouring and sleeting. Two younger and stronger thruhikers (Triple Crowners at that) got hypothermic. I survived much better in my shakedry. Moisture control is much more difficult hiking than bicycling. Shakedry is fragile and expensive and not for everyone.
I am amazed when people say nothing will keep you dry and breath and yet in the same breath admit that they have not used any of these new fabrics. We have come a long way since waxed cotton.
