A deel (Mongolian: ᠳᠡᠪᠡᠯ /дээл [deːɮ]; Buryat: дэгэл [dɛɡɛɮ]) is an item of traditional clothing commonly worn by Mongols and can be made from cotton, silk, wool, or brocade.
The deel is still commonly worn by both men and women outside major towns, especially by herders.[1] In urban areas, the deel is mostly only worn by elderly people, or on festive occasions. The deel appears similar to a caftan or an old European folded tunic.[1] Deels typically reach to below the wearer's knees and fan out at the bottom. They come in a variety of colors but are most commonly blue, olive, or burgundy.
