Men's CARHARTT FR Flame Resistant  Double Knee Distressed Bib Overalls 43 X 33. The overalls do not have a size tag so I input with actual measurements of waist and inseam.  My best guess is an XL and possibly Tall as I believe they may have a drop crotch. There is a tag that indicates - INDURA Ultra Soft Flame Resistant Fabrics by Westex - 88% cotton and 12% nylon.  Overalls have wear, holes, staining, some "ripples" in the elastic straps and heavy wear on the back of hems.
