Vintage Coat St John's Bay Corduroy Polyester Blend Size XL With Pockets Flannel

This older jacket is in amazing condiion. Corduroy on the top, polyester blend body, and a bit of flannel on the bottom of the lining. It has 4 generous sized cargo pockets that have hook and loop closure. The size is XL, see measurements in my pictures. Made in Korea. I'm not sure of the age, 80s or 90s.
