Men's Aviator Jacket, the symbol of timeless and classic style that a man or woman can wear today, is still a must-have in their wardrobe. This attire was originally designed to protect Air Force personnel from the cold sensation in the cockpit. As a result, they opt for leather as their primary material. With its timeless classic appearance, leather can also provide better insulation at a lower cost. However, as technology advanced, the altitude increased, and sheepskin replaced the lining to better trap.
