The Alangan Mangyans live in the municipalities of Naujan, Baco, San Teodoro, and Victoria in Oriental Mindoro, and in the municipality of Sablayan in Occidental Mindoro.
The name Alangan was derived from the name of a river and mountain slopes in the upper Alangan Valley [Leykamm, 1979].
The women traditionally wear a skirt called lingeb. This is made of long strips of woven nito (forest vines), and is wound around the abdomen. This is worn together with the g-string called abayen. The upper covering is called ulango, made from the leaf of the wild buri palm. Sometimes a red kerchief called limbutong is worn over the ulango. The men wear g-strings with fringes in front.
