This is a denim coverall from Big Mac. It is a dark blue, heavy (though not stiff) denim and there are thick pads that run from the knee to the bottom hem. The coveralls do not have their original tag so I don't know the actual size though some measurements follow to help with fit.
The cuff of the sleeves have hidden buttons for safety. It has a metal zipper and snaps at the front and elastic at the back of the waist. There are a lot of pockets including those at the sides like you find on painter's pants.
I don't see any top meaningful signs of wear and the coveralls are in very good condition.
