Shatnez (or shaatnez, [ʃaʕatˈnez]; Hebrew: שַׁעַטְנֵז šaʿaṭnēz) is cloth containing both wool and linen (linsey-woolsey), which Jewish law, derived from the Torah, prohibits wearing. The relevant biblical verses (Leviticus 19:19 and Deuteronomy 22:11) prohibit wearing wool and linen fabrics in one garment, the blending of different species of animals, and the planting together of different kinds of seeds (collectively known as kilayim).
