Tim's onto something. The mit-in-a-mit system (except we didn't call it that back in those days) worked for me when I was in the oil patch.
You need a good, thick cowhide outer. They're not much use for fine tunin' like hand tightening a nut. Then you gotta take them off and gut it out.
But that gives you a good excuse to go hide in the truck for a while with the heater blasting.
Also came in handy for that old rope tow at the Drayton Valley ski hill.
You could burn up a pair of dainty ski gloves in a half hour trying to get on that contraption.
I still got my old pair in the hunting pack. I pull them out when I'm running the Armstrong ice auger at Pigeon Lake.
