We had bought this coat about 35 years ago, used for fall fishing season around Lake Ontario. It is well used and has about half a dozen holes of various sizes, however the polartec insert vest has only been worn a handful of times. It is a UK size M and a Euro size 50. It fits like a large/xl, but I will include size measurements as follows- across the chest, armpit to armpit is 25 inches, top of neckline to the bottom of the jacket is 33 inches neckline to the end of the sleeve is 31 1/2 armpit to the end of the sleeve is 19 1/2.
