I'm glad somebody else mentioned using a "cooler" to keep things warm. I had friends laugh at me for suggesting this, I resisted the temptation to call them idiots and remind them that a cooler is just an insulated box.
I think putting some equipment into a big cooler with a hand warmer when I have to work outside in the middle of winter is a great idea, especially tools that are truly miserable to handle when they are at Sub-Zero temps.
We use the small size igloo coolers when we're washing and packing root veggies in the fall. Not really possible to keep your hands dry, so we fill a cooler with hot water and dip our fingers in periodically. Works great.
