I have had a pair of Montane prisms, but found I needed a liner with them on cold days, but I do suffer from cold hands. When I lost them I didn't replace them. I actually swear by sheepskin mitts, they keep a bit of warmth when wet and I have a spare pair for if they get really soaked through. I also have a weird pair of Rab ones, they look like mitts but the inside is divided into fingers so they feel like gloves. They are supposed to be the best of both worlds, mitts with a bit more manoevreability. I'm not totally convinced, but they are pretty warm.
