1960s Plaid Polyester Blend Mens Pants, Vintage Slacks, Size 36 Waist. There are no labels, except for washing instructions. I believe they are a cotton polyester blend. Great design & in great shape. The epitome of mid century modern style. These pants do not look to have been worn. Also the plaid hues & tone are softer than what is shown in some photos. Excellent!
