Babylonian Talmud (Moed Katan 15a, and Eruvin 84b), where the Aramaic word used for "habit" is "sudera" (Latin: sudarium) and which was usually worn by Jews with a central cap known in Aramaic as "kumtha." In Kiddushin 29b, there it mentions the Rabbi who refused to wear a "sudera" (habit) on his head until he was married, meaning, his head was only covered by a cap. Cf. Smith, J. Payne (1903). A Compendious Syriac Dictionary (in Syriac). Oxford: University of Oxford., p. 364, s.v. sudarium.
