This is a nylon-bodied, quilted, insulated jet cap from the 90s Polo Sport Ralph Lauren. It features a leather strap. I haven't seen another one like it, so I think it's quite rare. There is some soiling on the front; please consider cleaning if you are concerned. - Brand: POLO SPORT - Color: Khaki - Style: Flight Cap - Material: Nylon - Features: Quilted design - Adjustable: With back strap Thank you for looking.
