alfablue said:Gore fabrics have a lifetime "keep you dry" guarantee, and they genuinely live up to it (regardless who manufactured the garment). Over the years I have tested this out a few times and I have always got a new replacement or a full refund when they have failed, with no quibble and no receipts - for this reason I would always choose Gore over other fabrics.
Yes, precisely my experience. Have had a number of new jackets 'gratis' because of this. You could argue that that's good but my view is contrary and look at it from the perspective of I've never had a good Gore-tex jacket. One, depressingly, lasted less than 12 months. Since then, I've used a variety of other breathables from different manufacturers. All have been adequate and cheaper than Gore-tex and seemed to have stood the test of time better (I could always tell when the Gore's had failed).
With regard to breathibility - In our climate, especially in summer in the rain you are on to a loser if you think you're going to be bone dry. Try a hard crisp winter walk if you want to see how well they really work.
