The material used is sheepskin (sheep leather) mouton, which is exceptionally soft among genuine leathers!!! It has a soft texture and a gentle touch, which is its main appeal! It creates a soft elasticity and feels incredibly comfortable against the skin, like human skin. Mouton creates a thick layer of air between its fibers, maintaining exceptional warmth. Its heat retention is higher than any other fiber, keeping you warm even on cold winter days. Furthermore, it excels in its ability to adapt to changes in temperature and humidity, insulating when it's cold and absorbing and releasing moisture when you sweat, making it comfortable even in summer.
