Mine did this, albeit when cleaned it would smell fine, but after 1 ride the funk of my worst arm pit smells would return.
Helly Hansen fabric use to be called Smelly Hansen by my LBS due to it having similar properties.
I cleaned mine then sold it to solve the problem.
I now use an Endura jacket, which whilst not as good does not smell so wins in my book.
Sorry to have no actual factual explanation for the Gore-smelly-arm-pit-syndrome. I suspect I used fabric conditioner when cleaning my Gore jacket which Gore says not to use, suspect something happened as a result.
