Budenovka (Russian language: Будёновка, budyonovka) is a distinctive type of hat and an essential part of the communist uniform of the Russian Civil War and later. Its official name was the "broadcloth helmet" (шлем суконный). Named after Semyon Budyonny, it was also known as the "frunzenka" after Mikhail Frunze. It is a soft, woolen hat that covers the ears and neck and that can be worn under a helmet. The cap has a beak and folded earflaps that can be buttoned under the chin.
The hat was created as part of a new uniform for the Russian army by Viktor Vasnetsov, a famous Russian painter, who was inspired by the Kiev Rus helmet. The original name was bogatyrka (богатырка) - hat of a bogatyr - and was intended to inspire Russian troops by connecting them with the legendary heroes of Russian folklore. Bogatyrkas were meant to be a part of a new uniform, so they had already been produced during World War I, but hadn't been officially adopted. Another version, quite popular in Russia, is that bogatyrkas were designed for a military parade as a part of a "historical" stylized uniform (which also included an overcoat with "designer" cross-pieces, which also were used in the Red Army to a limited extent). Some Russian historians even speculate the parade in question was a supposed victory parade in Berlin.
