This is an original vintage U.S. Air Force issue HGU-38/P extreme cold weather survival cap. It is in excellent unused condition. Insulated and very warm. Original label indicates a size small. This is a size 7. Hat has fold down ear flaps and is complete with the chin strap. Best guess is Vietnam vintage or earlier. High quality you can get. Will keep your head warm in the coldest of temperatures. Priced to sell. Don’t miss it.
