The jacket of the the BG IMO must have knobs, because the photos show the jacket is spreading round his belly. With a closed zip it wouldn´t.
Try this one....Rothco concealed carry soft shell jacket with a two way zipper so it would connect in the middle like you are describing. It also had a hoodie....tada. He may have the hoodie of the jacket up, rather than wearing a hoodie under the jacket.
