Extra mittens and gloves. If you’re working otdoors, you’ll appreciate keeping your hands warm.

When I worked in circumstances like that, I used super large mittens, and they were worth it. You should pick up mittens that have a leather outer shell, removable soft inner mittens and enough space for you to also use extra gloves inside. In cold weather (-25 °C), I used all three layers. When it was warmer (-10 °C), I just used the outer two layers.

When the temperature begins to approach zero, sunshine can melt some of the snow during the day, which will make your mittens wet and your life miserable. For situations like that, you should make sure the outer layer of your leather mittens can deal with water. If that’s not an option, you should bring some spare mittens with you. When the mittens and gloves get wet, you need to try to dry them during breaks. After work, hang them to dry in a warm place, so that they will be ready for the next day.
