My new Dianese's are goretex and supposedly wind/waterproof, but I'm not really convinced.
Are the heated grips not enough? or are they heating only the insides of your hands and the backs are still getting cold?
I'm seriously considering putting the new gloves on ebay and just getting a pair of gerbings.
they work well, but the second you take a hand off (lift fingers to shift or brake), the heat is gone and takes a bit to come back. I was looking at maybe adding them to help with that, but it may not. The lowest it's gotten to over the last few weeks was 34... the grips worked great for my 40 or so minute commute.
