I had two pairs of gloves when I used to hunt ducks and geese.
One pair were thick rubber with felt lining, and they were long enough to reach my elbows. I bought them at a hardware store years ago. I think they were originally made to handle chemicals? I used them only for setting and picking up the decoys later in the season when the temps were too cold for getting your hands wet.
The second pair was just a thin leather glove. Not the best for warmth, but it kept the wind off, and worked fine with handling the shotgun. Actually they were the same gloves I used for rabbits, squirrels, and pheasants.
I bought a pair of those Neoprene gloves made for duck hunting when they first came out on the market, and they work good for handling the decoys in the cold, but I found they made my hands sweat like crazy if I wore them all day.
