This lovely three-volume edition, including machzorim for Rosh HaShana, Yom Kippur, Pesach, Shavuot, and Sukkot, makes a special gift to enjoy the year round. Koren Mahzorim are the clearest and most accurate holiday prayer books available.

The classic Koren layout emphasizes major public prayers and illuminates their underlying meaning.
