Breathable stuff will leak sooner or later. Rubberized stuff will get you wet with perspiration from the inside. Nothing's perfect - you choose your poison. The wettest I've ever been offshore has been with GoreTex FWG that was more like a sieve than any real protection - admittedly a long time ago but I've been skittish about the material ever since. If you really want to stay dry wear something waterproof (rubberized) and some fleece to absorb moisture. On my boat I carry an expensive breathable FWG for when it's mildly wet and some Nova Scotia fisherman's rubber gear for when it's really wet.
