That is what has happened to your Mocha. The outer layer has lost its original DWR, and while spray-on materials work pretty well, they aren't as good as the original coating and tend to wear off quickly. Maybe the face fabric on your jacket has become slightly frayed, too, impeding its ability to hold the Revive-X (you might also try NikWax's TX Direct Spray-On, just to see if for any reason it works better). The end result: When it rains, the outer layer becomes wet and water blocks all its pores, effectively sealing the garment. The Gore layer can't transfer moisture to the outside of the jacket, the moisture condenses inside the jacket, and you feel clammy. The cruel irony is that the Gore layer is probably working just fine; it's the supporting cast that has failed.
So, it might be time for a new jacket. Today's DWRs are more durable than those of six or seven years ago, so you might get more wear out of a new jacket than the Mocha. Plus, most Gore-Tex jacket makers have switched to what is called Gore-Tex XCR, which is both lighter and more breathable than the "classic" Gore-Tex in your old jacket. One good example: L.L. Bean's Mountain Guide Jacket, just $299.
