2011年2月24日 · During a visit to Eretz Yisrael, the previous Chabad Rebbe came across a striping pattern in which the second stripe was wider, rather than the third stripe as in typical talleisim. He liked the pattern, bought the tallit and gradually many Lubavitch Chassidim followed suit and this design came to be known as the Chabad Tallit .

I was told it's because the wife of the Lubavitcher Rebbe did not like the way the decorative knots on the side edges looked (they look unfinished), and would cut them off of his tallis and put in a regular seam. So he started folding the knots under so they would not be visible (i.e. would not look bad) and the other chassidim copied him.

The Alter Rebbe. Once, on Yom Kippur morning, the Alter Rebbe took off his tallis and kittel and went to the edge of the city. Once there, he cut some wood to make a fire in order to cook soup for a woman who had just given birth and had no one to help her. In a sichah 2 the Rebbe added:

The main difference between the two is size. The Rashab Tallis is significantly wider. Ben's Tallit shop says it is the widest that he sells ("even wider than a size 90 Yemenite Tallit"). It is therefore significantly more expensive because it has the extra material. It is a recent thing to have such variations marketed at all.

I have been told by Chassidei Chabad that prior to their current pattern, the sixth Lubavitcher Rebbe wore a munkaczer tallis. What does this tallis look like? Here is a link that shows you the Munkaczer pattern. So it's not really different from the modern Chabad tallis? Gershon, I see Chabad tallitot often enough.

In Piskei HaSiddur the Alter Rebbe writes that for an adult the tallis katan should be a cubit by a cubit — 24 thumbbreadths (48 cm. = 19 ins.) by 24 thumbbreadths — both front and back, apart from the shoulderpiece on either side of the neck.

Menachem Mendel Schneerson [a] (April 5, 1902 OS – June 12, 1994; AM 11 Nissan 5662 – 3 Tammuz 5754), known to adherents of the Chabad-Lubavitch movement as the Lubavitcher Rebbe or simply the Rebbe, [2] [3] was a Russian-American Orthodox rabbi and the most recent Rebbe of the Lubavitch Hasidic dynasty. He is considered one of the most ...

The Rebbe was wearing his kittel, the special Yom Kippur robe, and had lifted his tallis over his head. The entire congregation had their eyes focused on him, watching him while he stood absorbed in thought. Suddenly, the Rebbe removed his tallis and his kittel and strode quickly out of the synagogue.

2012年9月14日 · The Rebbe would lift the edge of the tallis to just under his eyes and a cry, like a lion’s roar, would emerge with the beginning words: “Lamnatzeach livnei keirach mizmor.” The Rebbe would throw the tallis back over the entire bimah, covering the pidyonos as well, and a loud hum followed throughout 770 as the congregation chanted the ...
