Except for the breathable part not very scientific testing. Still interesting and amusing just the same. Seth is certainly not a Gore fan and lists Pre-Cip as $79 retail from Campmor which must be a close out.
I've seen people swear by GORE-TEX like it's some kind of rainwear miracle. Yes, I know, in its day it was a fabric revolution. Waterproof and breathable, ooooooh. Never been done before, blah blah blah.
Please. That was 1976, people. You're still going all googly-eyed over expanded Teflon laminate membranes? Well, that's sad! Plenty of new waterproof/breathable options are out on the shelves these days.
