Mens Flight Jacket, the symbol of eternal and classic style that a man or woman can wear today, is still an essential range of their closet. This clothing was originally designed to protect Air Force personnel from the cold in the cockpit. As a result, they select leather as their primary material. Furthermore, because of its timeless classic appearance, leather can provide better insulation at a lower cost. However, as technology advanced, the altitude rose, and sheepskin replaced the lining to better trap the internal heat.
