I've been using those blue rubber cleaning gloves underneath my regular gloves lately because it hasn't been very cold (a few degrees below zero). I normally would need to pull out my mittens in this temperature but with the waterproof layer underneath I don't get the freezing cold evaporation on downhills which is what I normally need the mittens for.
My hands are all wet inside but it doesn't really bother me, or I should say it bothers me less than riding with mittens.
