I use some leather SWIX XC ski gloves. They are thin but warm and snug fitting. Reinforced palm and fingers. Lined with thinsulate. Problem with cloth or wool gloves is that the riser slips in your hand. But the leather gloves do not slip in your hand. Interestingly, I use these as a shooting glove too. I just put them on, no tab or shooting glove, and they work fine. At least for me. YOu have to get a pretty snug fit, however, or you're sloppy on the string. I tried a pair of Wells Lamont unlined leather gloves but too loose and sloppy.
