The tallit katan ("small tallit") is a fringed undergarment worn by Orthodox and Hasidic Jewish males. It is a poncho-like garment with a hole for the head and a specially knotted ritual fringe attached to each of the four corners. ^[1]

The custom of wearing a tallit katan is based on a verse in Numbers 15:38–39 which exhorts Jews to "remember[ance of] all the commandments of the Lord."

The tallit katan is also known as arba kanfot (Yiddish/Ashkenazic Hebrew: arba kanfos), literally "four corners," or tzitzit.
