Fishing gloves

I sometimes use latex gloves.

Try divers gloves possible should have good feel and water proof

If it's dangerous cold, your hands have to stay dry. Rag wool stays warm when its wet and you just cut away the tips for the digits you need. The fold over mittens and thumbs with handwarmer pockets if you're fancy.
