I'm also one that does not like using a glove on my bow hand when shooting. However, when it's bitterly cold I will use a "liner" glove, and keep a hand warmer in my pockets. Now I use the Stika Fanatic jacket with a kangaroo pocket - it's an outstanding jacket for on-the-stand whitetail hunting. Something else that I used to do many years ago, was to use a wool sock and cutout the toes for my fingers, and make a thumb hole - helps keep the cold air off the wrist areas.
Some other things you can do to try to maintain body heat while on the stand - use hand warmers around your kidney areas and protect your neck/head for escaping body heat, and as I said previously keep your wrist areas protected.
