My hunting partner thought I had hand warmers in my mitts! I broke these in on a December Idaho whitetail hunt. It was an average of 10 degrees, and my hands stayed toasty warm. I’m a Georgia native, so needless to say, I was not acclimated to the cold! I loved how I could just pop the ends off when I needed to use my fingers, but they held on to the warmth from my hands when I put them back on. Even through constant snow, wind, and even ice, my hands stayed dry and warm.
