TSK · Exodus 39:28

Now these are the garments that they are to make: a breastpiece, an ephod, a robe, a fitted tunic, a turban, and a sash. They are to make holy garments for your brother Aaron and for his sons, that they may minister as my priests.

You are to weave the tunic of fine linen and make the turban of fine linen, and make the sash the work of an embroiderer.

Linen turbans will be on their heads and linen undergarments will be around their waists; they must not bind themselves with anything that causes sweat.
