When airplanes were first invented, they lacked enclosed cabins and were exposed to the wind. To combat the chilly conditions, pilots needed a hat that would keep their ears and heads warm. Additionally, they required a convenient place to store their goggles when not in use. As a solution, the aviator hat was created. Typically crafted from leather for enhanced protection, these hats continued to be worn even as planes transitioned to fully enclosed designs. They remained a staple accessory through World War II until they were eventually substituted by caps for commercial pilots and helmets for military personnel
