I live and work in Canada, in some of the coldest temps on earth. Glove liners are a must. Warmers help. The key is a breathable glove. Moisture is the enemy. Most gloves trap moisture and that will only speed up the cold effects. Using an over glove or mitt style can help, but for an electrician, provides no dexterity. Wool gloves, rubber dipped, help a lot. Most are a little too rigid when cold, hard to find good, flexible ones. Milwaukee heated gloves are the worst. They trap moisture, make your hands sweat and are uncomfortable. Sent from my iPad using Tapatalk
