I vote for the strip as well. There was a photo on What are you wearing today thread, I think it was yesterday. It was an orangey type jacket with curved opening and it had similar closures. Was going to post here for reference, but I think you participate in that thread as well, so didn't want to spam too much. Looks like each button is reinforced, but that seems like very thick leather. With the sheepskin I think you need the strip.
