Must Tzitzit and Tallit Be Made of Wool

According to the Shulchan Aruch, the only way to fulfill the Mitzvah of Tzitzit from the Torah is with a Tallit made of wool. While the word wool is not mentioned explicitly in the Pesukim regarding Tzitzit, Chazal derived from other Mitzvot that the word "Begged" in the Torah (garment) denotes only a sheep’s wool. Any other fabric would only be obligated in Tzitzit M’drabanan, from a Rabbinic Mitzvah. However, The Rema argues and rules that almost all fabrics, including cotton, fulfil a Torah obligation. Thus, there is a divergence of opinions between the Sefaradim and the Ashkenazim. Nevertheless, Rav Moshe in a famous Teshuva in Iggerot Moshe (Vol. 1 and 3), rules that even Ashkenazim should be strict and fulfill the Mitzvah using wool. He cites a Gemara in Menachot which states that Tzitzit is, in effect, a voluntary Mitzvah. That is, one is not obligated to go out of his way to wear a four- cornered garment in order to fulfil the Mitzvah of Tzitzit. However, the Gemara continues and says that in an "Idna D’Ritcha"-a time of Divine anger, Hashem even punishes for not fulfilling a voluntary Mitzvah. Rav Moshe reasons that since we don’t know if this is a time of wrath, it is best to fulfil the Mitzvah in the optimal way according to all the opinions, using wool. Chacham Ovadia points out that if Rav Moshe recommended that Ashkenazim, who generally follow the lenient opinion of the Rema, wear wool, how much more so Sefaradim should be scrupulous to do so. Moreover, wearing a wool Tallit also enables one to avoid the dispute amongst the Rishonim (early authorities) as to whether a cotton Tallit requires strings made of wool or cotton. While most authorities agree that wool strings are required, the MaHaram M’Rotenberg held that a cotton Tallit requires cotton strings. Therefore, all of the Poskim say that one should try to use a wool Tallit, especially today that there is a light-weight wool that is not too hot in the summer. Chacham Bension writes in Or L’Sion that if someone feels that any wool is too hot for him, he should at least wear it in the morning and then change into cotton Tzitzit for the rest of the day. The Vilna Gaon had an unusual position on this issue. He was careful to only wear a cotton Tallit. This is surprising, since he was so scrupulous at following all of the most stringent positions. The Chazon Ish and the Steipler Rebbe also followed his path. Several explanations are offered as to why he did so. One possibility is that the Gaon would wear a linen undershirt, and he was concerned that wearing a wool Tallit over it might constitute a problem of Shatnez according to Rabbenu Yonah. The weakness with this theory is that it does not explain why he had to wear a linen undershirt. Others say that since the Vilna Gaon would wear his woolen Tallit Gadol all day long with his Tefilin, he was not concerned regarding the fabric of the Tallit Katan. The third theory is that he wanted to demonstrate to the common people, who thought that only wool was obligated in Tzitzit, that even cotton is obligated in the Mitzvah. It goes without saying that everyone should wear a Tallit Katan. One who does not is taking a great risk. As we live in dangerous times, which could qualify as "Idna D’Ritcha," the Tallit Katan serves as a spiritual protection, no less important than the other security measures we take to protect ourselves. Everyone should make sure they follow Shulhan Aruch and have a wool Tallit Katan with wool strings. If someone refuses and gives an "ultimatum"-either cotton or nothing, of course, cotton is preferable to nothing. However, just as a person tries to do other things in his life in the best fashion, so too Mitzvot should be performed in the best possible way.
