A kittel (Yiddish: קיטל [ˈkɪtl̩]) is a white linen or cotton robe worn by some religious Ashkenazi Jews on holidays, in the synagogue or at home when leading the Passover seder. Grooms sometimes wear kittels. It is also customary for Jews to be buried in a kittel, at which time it is referred to as a tachrichim.
