I have this problem with warm blood getting to the ends. I made a pair of mittens that you would hang on the pack belt that goes around your waist. You need to find sheep hide, it must not have been sheared. This is super importment, NOT sheared, ever!!! You can make the mitten large enough to place your gloved hand into or as I did make it to fit my bare hand. I have put a hand warmer into each one, but it was to hot! Then walking or on stand my hands can be slipped out to shoot. These babies WILL keep your hands warm. Make them a little larger than needed. Go to an Amish harness shop to get them sewed. I forgot to say, the wool goes to the inside!
