WorkWear Question: what warm thin gloves do you use?

I work outside in weather that is often below zero. I am very warm everywhere except my hands. I can’t wear thick gloves because I lose dexterity.

I don’t like using hot hands packets because they always leave that gun powder black residue on everything, especially if I leave them in a pocket. Had one burst on me before. Anyone have recommendations for good thin-thermal lined gloves or other products that work for them?
