This military cap with foldable flaps is a combination between a baseball cap and winter cap. The top portion is a ball-cap construction with a front bill. The bottom half is a fur lined extension to protect the neck from the elements. The entire cap is lined with a quilted fiber for protection. There are snaps at the sides to flip the ear and neck protector upward. The tag on the inside reads a serial number which may identify which military it was from as well as the date of manufacturing- April 1971. These hats will protect both kids and adults from the cool weather! Wear some history and stay warm.
