Vintage Sweatshirt

Paper tag, made in the USA. Boxy fit. Slits on both sides. Gray sweatshirt material with corduroy for collar. Sleeves are short, almost quarter sleeves. The zipper on the neck is coming apart some (shown in pic), but I wore unzipped and didn’t notice it for a long time. No other stains/damage. Measurements are laying flat pit to pit & length.
