I prefer to not use gloves but it beats losing all feeling in your hands. Then you are really going to shoot poorly! I like thin ones. I have got a fleece pair that is very warm and has rubberized grips on the palm. They are really nice for shooting the bow. Before those I was just using those thin cotton ones. They did not help all that much.
I wear a glove on my hand that holds the bow, but for my trigger finger hand, i tend to just keep it in my pocket to keep it warm. When it gets really cold I stick one or two hand warmers in the pocket. It works to keep it warm, but allows me to keep it ungloved. Not only do I like it for the trigger finger, but it helps me to feel my anchor point too.
Want a quick and inexpensive call for Moose? Take an empty 32 ounce coffee can, and make a small slit in the bottom, only about a quarter inch. Then, take one of those really big red rubber bands, the ones that go around big folders. Cut the rubber band to make one long piece.
Now, thread one end of the band and tie a knot on the outside of the can so it won't pull through. Cut the band off on the other side so it is even with the top of the can.
Now, wet your finger,...
