One who makes a neder prohibiting clothing is permitted sackcloth, sheets of cloth, and heavy fabric. [If] he said: “Konam, wool [from] coming upon me,” he is permitted to clothe himself with wool shearings; “Flax [from] coming upon me,” he is permitted to clothe [himself] with stalks of flax. R' Yehudah says: All depends on the person making the neder. If he was carrying a load, and he perspired and smelled badly, [and] he said: “Konam, wool or flax [from] coming upon me,” he is permitted to clothe [himself with these], but is forbidden to carry bundles [of these] on his back.
