Chabad Tallit and Tefillin Bags
Chabad, a Chassidic group in Judaism, has many of its own customs and members often choose to have designs of their movement’s headquarters on their tefilin and tallit pouch sets.
770 Design
Members of the Chabad Chassidic group, also known as Lubavitch, often choose a tefilin and tallit pouch set which incorporates a design of the organization’s headquarters building at 770 Eastern Parkway, in Crown Heights, New York. One of the customs of Chabad is to use two different sets of tefilin: - regular tefilin known as Rashi, and the other set, known as Rabbeinu Tam. This means that it is important to have two tefilin bags, and a large enough tallit bag to hold both sets of tefilin. Chabad tefilin are also usually slightly larger than other tefilin, so remember to specify this when purchasing pouch sets if they are for a member of Chabad.
Rabbanue Tam
Rabbeinu Tam was the grandson of Rashi and he had a different opinion as to the order that the parshiot (small scrolls with biblical verses) should be put into the tefilin. Due to this difference of opinion, Chassidic group like Chabad, some Sephardim, as well as men who are particularly scrupulous to keep the mitzvoth properly according to the different opinions, put on each set of tefilin, one after the other. They usually keep them in separate tefillin bags so that they are not confused, because from the outside there is very little difference in the appearance of the tefilin.
