Later, the sheepskin lapels of the malakhaevs began to be cut vertically on the sides, the resulting "ears" could be tied at the back of the rider's head when the weather warmed. The legendary men's caps with earflaps, which became popular in Russia in the 16th-17th centuries and were called "treukh", originated from such malakhais. It is noteworthy that now a cap with earflaps is a symbol of a man's cap for the winter, but at first it was mainly rich Russian women who sported them, who adorned their coats with expensive fabrics and stones.
