On most duck hunts, I don't use gloves (can't call with them on). I like to use a hand muff to put my hands inside while not calling or shooting. If cold, I put hand warmers in the muff...if really cold, I break out the electric heated hand muff. I have two batteries for it and that will last me 6 hours on high.
On late season hunts where I call very little. I might put on some water proof shooting gloves or Camo Skins, depending on what is in the gear bag. For the most part, I am just not a glove person while duck hunting.
