This is a rare one!   The only other I've been able to find on the internet was sold in 2010!   Vintage 70s Levis orange tab barn / chore coat / jacket in a medium blue denim.   Has pockets on the front that have a lower zipper pocket as well.   Heavy duty Talon metal zipper up the front.   Button cuffs with the iconic copper Levis buttons.    Great condition with no issues found.   No size tag, so be sure to check the measurements below carefully.   All measurements have been taken with the jacket laying flat, so may need to be doubled.   

Shoulder to shoulder - 19.5"
Underarm to underarm - 24"
Waist - 21.5"
Shoulder to bottom hem - 29.5"
