Jack has a bald head and blue eyes. He stands at 6'3" and has a round build after recent years spent at a little more leisure though his skin still carries a darkened tan from years of hard work.

Jack is in his early forties, which in the Commonwealth is practically old age. He spent years working on the caravans that traveled in the northern Commonwealth but after they recently passed through Bunker Hill on the way to Diamond City he made the decision to stay on and help out with the growing commerce hub's marketplace.
