Is it a jacket? Is it a hoodie? No! It's Sam's Superhero Hoodie. If Dean has his signature leather jacket, then Sam has his signature hoodie: the Superhero Hoodie. It’s a cozy brown hoodie-jacket with black lining. (The hoodie-jacket has been identified as a Carhartt coat).
Brand Information: Carhartt. (model J25 - unique because it has a perforated lining inside the hood and down the inside sides of the zipper.)
