All I know is that last weekend I would have been dry had I had my Grundens. Every Gortex jacket I've had or still own has gotten me wet at some point or another, especially on the coast. And if you use as many eggs as I do in the fall, and then you wash your jacket, you may get the smell out, but your jacket will leak more easily. And the crap you put on to get it back to waterproof is just that, crap.
