A Talit Katan (small tallit) is a traditional Jewish garment, typically worn under the clothes. It's a small rectangular piece of cloth with fringes, or tzitzit, attached to each of its four corners. The tzitzit serve as a physical reminder of the commandments and Hashem's presence, as described in the Torah. The garment helps reinforce spiritual awareness and commitment to Jewish laws throughout the day. A Talit Katan that is kosher meets specific religious standards regarding the fabric, the making of the tzitzit, and how they are tied.
