From Manners and Customs of the Bible:

The φελόνης was a thick upper garment corresponding to the Roman panula and was used in traveling instead of the toga as a protection against the weather. It was sometimes worn by the women as well as by the men. It was usually made of wool, though occasionally of leather, and was a long sleeveless garment, made like a sack, with an opening for the head.
