Rekel or Lang Rekel (plural rekelech) is a type of
coat worn mainly by
Hasidic Jewish men during the Jewish work-week (Sunday-Friday). Rekelech are generally made of a black or navy
wool blend or of
worsted wool. Today some are made of 100%
polyester. Interestingly, many Hasidim in the past did not wear wool clothing, and the new polyester rekelech actually make it easier to keep this old custom. They tend to be light, and thinner than the average
suit coat, since they are generally worn throughout the year. Rekelech are usually sold as part of a suit with matching pants and a vest (waistcoat, זשילעט), though they are also sometimes available as suit separates.
