Cotton is used to make the King Arthur Charlie Hunnam Jacket. Outside features the stitching as the detailing that you can see on the sleeves and shoulder area. There are two toggle buttons for the front closure. It also has two inside pockets with viscose as the lining. There is no collar and looks exactly how it is pictured.
