The Sagum was the principle robe or covering (cloak), worn by Roman Legionaries (1st thru 3rd A.D.) (as well as Officers and NCOs). Designed to help keep them warm, The Sagum was made of dyed Red wool. Only military personnel wore The Sagum. It was designed to extend as far as the lower back calf of the leg. A leather clap and hook was often used by Enlisted Men (with brass or precious metal) being used by Upper Ranks. The Sagum was also covered in Lanolin (a chemical which made The Sagum water-resistant). They were not worn past the mid-4th Century A.D.
