Carhartt Black Double Knee Overalls

Carhartt double knee black duck canvas overalls. I’ve had these for many years and they have about 100 wears on them. I bought them back before they moved production out of the country so I believe them to be USA made, although I cannot find a tag. I believe they are 34. I am 6’2 175lbs and they fit me well. Excellent condition no rips or tears anywhere. See pics for exact measurements. Thanks for looking.
