A ushanka is a traditional Russian fur hat designed for extreme cold, featuring signature, foldable ear flaps that can be tied at the chin for maximum warmth or up at the crown for versatility. Originating from 17th-century Slavic designs and popularized by the military, it protects the head, ears, and neck from sub-zero temperatures. 
 
Key Aspects of the Ushanka:
Purpose: Engineered for arctic-level winters to protect the ears, chin, nape, and neck from freezing temperatures and wind.
How to Wear: The ear flaps can be worn down for maximum warmth, tied behind the head ("ski-style") for better visibility, or tied at the top for a classic look.
History & Origin:
While inspired by ancient, nomadic, and Slavic fur hats (like the 17th-century treukh), the modern, standardized ushanka was adopted by the Soviet Red Army in 1940 following the Winter War, later becoming a staple of Russian culture.
