Kolpik

A kolpik is a type of traditional headgear worn in families of some Chassidic rebbes (Hasidic rabbis), by unmarried children on Shabbat, and by some rebbes on some special occasions other than Shabbat or major holidays. The kolpik is made from brown fur, as opposed to a spodik, worn by Polish chassidic dynasties, which is fashioned out of black fur.

It is seen as an intermediate level garment between Shabbat and weekday dress.

The days that some rebbes don a kolpik include:
