I sometimes hunt in quite cold conditions -15 C. or so . I use gloves with cutoff fingers that have the mitt that folds down over the ends I'll see if I can post some pics. I also bring things like nuts and raisins to snack on. The smell of the salt likely doesn't hurt your cause ,either. (nothing loud) Your body warms up when you are eating. Warm head is also the key. If your head and body core aren't warm ,it robs the heat from the fingers and toes. I sometimes bring an extra coat that I wear like a blanket wrapped around while sitting . If I hear something coming ,I let the coat slip off my shoulders on to the ground . This works pretty well for staying warm ,as you are kind of crouched and huddled. I've only done this in remote areas where you don't get all of the peripheral noise from highways , etc. , so you can hear things coming before you see them. You could also tuck a piece of fur in your pocket. It's amazing how much warmer it is with a bit of rabbit fur in there.
