kalvokehittejä
Kalvokehittejä refers to a Finnish term that translates to "calf heaters" or "calf warmers." Historically, these were garments worn by farmers and laborers in Finland, particularly during the colder months, to keep their calves warm. The design typically involved knitted or fabric tubes that were pulled over the legs, extending from the ankle to just below the knee. They were often made from wool or other insulating materials to provide warmth and protection against the elements, especially when working outdoors in fields or barns.
The use of kalvokehittejä was common in rural settings where prolonged exposure to cold was a reality
