Key Features

• Design: It is a soft, non-rigid cap made of khaki fabric (often cotton or wool) with a padded lining for added insulation.
• Packable: The cap can be easily folded or worn under a helmet without losing its shape.
• Earflaps: The cap features fold-down earflaps lined with wool to protect the ears and neck.
• Wearing: The flaps fold up and fasten with a buckle when not needed, making the cap resemble a standard field cap. During World War II, they were often worn under helmets by American GIs.
• History: Although the design dates back to 1937, variations remained in use during World War II and the Korean War.
