Working comfortably in cold conditions starts with warm and dry underwear. The three-layer system starts with the bottom layer. It has to ensure that your body heat and transpiration moisture find their way to the outside as quickly as possible. So be sure to wear a moistregulating fabric on your body to keep your skin dry. A wet bottom layer severely cools off the body, a problem that can be easily avoided by wearing for example polyester or a thin type of wool. This makes sure that your own sweat and body heat are disposed of without you getting wet yourself. Wearing the right type of bottom layer prevents you from cooling down too quickly when you do decide to take a break. Work socks, thermal socks, boxer shorts and thermal underwear are among the essential elements in the wardrobe of every professional.
