Leather cold-condition gloves and mitts are insulated to keep hands warm in cold environments. They are made of animal skin or synthetic materials. The insulation material and thickness affect overall warm and dexterity of the glove, with thicker gloves being less dexterous than thinner gloves. Liners and outer layers and coatings improve wind and water resistance. Leather provides a balance of abrasion resistance and dexterity and is used when working outdoors or in cold environments in general construction, maintenance, and when driving large machinery.
