In reply to Alpenglow:
I suspect this isn't just a power stretch issue as I have encountered similar with bog standard 100 weight fleece. My solution was longer sleeves on my water proof and a pair of goretex unlined mitts that I don as soon as it starts to get damp.
I'd be surprised if any mid layer is much better as they are meant to wick sweat out effectively so will do the same thing with rain water.
