A '''' (, literally "ball-hat") is a formal headdress with distinctive woollen pompoms worn since by Protestant women as part of their folk costume or in the three adjoining Black Forest villages of Gutach, Kirnbach and Hornberg-Reichenbach. The picturesque-looking red has become a symbol of the Black Forest as a whole, despite its rather local origins. The red pom-poms and white brim of the also is said to have inspired the top layer of the Black Forest Cake.
