Black Puffer pocketable jacket size M

I purchased and it and never have worn it brand new so still has the carry bag it fits into the label says 3XL but it is Asian size so please look at the measurements I am a size 4 and it is slightly large for me shell: Polyamide filling: down feathers I live in Vermont and would classify this as a 3 season jacket, not enough fill for really cold weather 2 way zipper 21" from armpit to armpit 30" length from shoulder to hem
