This is a British Army fleece jacket. I received an explanation of the official model, etc., but I forgot. I think it's something like a combat jacket. I wore it like an ECWCS, along with the US military's Level 7. I bought it as deadstock and wore it about 10 times. It is equipped with underarm ventilation and a drawcord around the waist. The size is M, and the actual measurements are about 54cm for the width and 80cm for the length. It's thick, so the fit feels a little smaller than the measurements. The tag says "United Kingdom." It's genuine, not a replica. Color: Green Pattern: Solid Zip/Buttons: Zip-up Hood: No hood Season: Autumn, Winter
