This traditional doctor bag is made from hand-stained buffalo leather that builds a rich, luxurious patina as it ages. The bag features one large gusset allowing for added flexibility when carrying things inside, especially when you need to carry oversized items. The zippered outside back pocket allows you to keep your phone or wallet close at hand. This soft, unstructured bag can be used as a day bag. An adjustable/removable shoulder strap can be worn on your shoulder or across your chest.
