In reply to Blizzard:
Probably Goretex XCR is the best I've used, mine is a Mountain Equipment mountaineering jacket.
While not being 'dry', a fluffy woollen jumper over a merino base layer kept me warm under a plastic bag waterproof a while ago when I was out all day bustling about doing fencing.
I think if you're comfortable and warm you don't notice any dampness too much.
Goretex XCR with pitzips is good in my experience, though, but you'll still probably get damp arms or something like that...
