Monastics may be wearing this over the head dress with the 13 crosses:
http://www.arabwestreport.info/year...astic-life-monastery-st-macarius-scetis:qulunsuwah [the Coptic headdress] He said all monks must wear it
from the crown of their head to the waist in order to remember the
meaning of the Cross (The Crucifixion of Jesus Christ)
Laymen may be wearing something similar/emulating the practice, especially older men, considered elders. Or they may have been monastic/held to monastic standards by their priest/bishop.
