I'm giving the arctic shield system gloves a try. I just picked up a set that I plan to use up north in a couple of weeks. The liner glove is very thin, and a mitten/glove goes over the liners, but can be folded back to shoot with just the liner gloves. I have a feeling they will work very well for bowhunting, however, I am skeptical they will keep my hands warm in 40 below.
