A version of the fez was used as an arming cap for the 1400–1700s version of the mail armour head protector (a round metal plate or skull-cap, around which hung a curtain of mail to protect the neck and upper shoulder). The red fez with blue tassel was the standard headdress of the Turkish Army from the 1840s until the introduction of a khaki service dress and peakless sun helmet in 1910. The only significant exceptions were cavalry and some artillery units who wore a lambskin hat with coloured cloth tops. Albanian levies wore a white version of the fez, resembling their traditional qeleshe. During World War I the fez was still worn by some naval reserve units and occasionally by soldiers when off duty. The Evzones (light infantry) regiments of the Greek Army wore their own distinctive version of the fez from 1837 until World War II. It now survives in the parade uniform of the Presidential Guard in Athens.
