The look of the modern ushanka was only developed recently. After the 1917 Bolshevik revolution, some units of the White Army who fought for the Tzar were given practical hats called Norvezhka, which literally translate as Norwegian. As implied by the name, the said design was made by the Norwegian conquerors of the North. The main difference of this hat from treukh is that the earflaps are longer. Also, it can be tied under the chin for an added warmth. If the weather is not too cold, they can tie the ear flaps on the top of the head to get it out of the way. After the proven usefulness of this design, it was soon borrowed by the Red Army as well. During World War II, all the fur factories were demanded to only make ushanka as needed by the Red Army. Several Russian uniform agencies still use ushankas to date. It is now in different color schemes such as black for the Navy and grey for the police. For extra decorum, the military uniform dress code requires ear flaps to be tied at the top. After its success in the military, ushankas made its way to the runway. Soviet hatters would own at least one such hat made of fur, beaver skin, deerskin, and materials of a similar kind.
