Maciejówka is a type of headgear popular in late 19th and early 20th century Poland. It is a round, soft cap made of cloth, with a short hardened peak, usually made of black or brown leather, often adorned with a decorative rope or braid. Originally part of traditional folk attire in many regions of Poland, during World War I it became part of the military uniform of the Riflemen's Association and the Polish Legions.
