The Leif Under Tunic Leif is made of natural, coarse cotton and is a basic garment for men from the early to the high Middle Ages across all classes and ranks practically as a must-have garment. Long sleeves, a straight cut with a round neckline, and slits at the neck and sides for higher dressing and wearing comfort together with the coarse look of the fabric give our medieval under-tunic a convincingly authentic look.
