" Backpackers need to get over this idea that you can be immune from your environment -- when it's wet, you should expect to get wet, because you will. It's much more fruitful to focus your attention on how you can minimize the effects of being wet."
you see, one can even tell the time by looking at the clouds. for instance, if it is raining, it is then time to get wet.
this is why they make wool.
or, if it's Really wet, polarstretch.
one will go a lot farther forward following andrew's advice than endlessly buying new parkas.
all that said. Great Test !
and, as a lot of things put on 2 dimensional digital graphs, in an extremely multi dimensional world and analog'ish world, it ain't going to give the whole answer.
case in point, i know for a fact that i can/will/do wear my e-vent parka a vastly lot more than i ever did my goretex ones, and that it runs dryer over a wider range of conditions than the graphs might indicate. and as indicated in andrew's insightful comments, i suspect sometimes the stuff leaks backwards.
once i found e-vent, i consider the fabric issue to be closed as far as me personally. it's good enough that any improvement is not going to increase my range or make a better experience. maybe yours, but not mine.
nice test though ! i like the comparitive condensation meters. if only it was as easy as wearing a different sock on each foot ....
