ulos

Ulos is a traditional woven cloth of the Batak peoples in North Sumatra, Indonesia. It is typically produced on a loom from cotton or wool and can be dyed with natural pigments. The length and width of ulos vary, and the cloth is valued both for its craftsmanship and its symbolic meaning in Batak culture.

The cloth plays a central role in social and ceremonial life. Ulos is commonly given as a blessing or sign of protection during important life events such as births, weddings, and other rites of passage. It is also used in welcoming guests and in other rituals to mark status, kinship, and communal ties. In funeral rites, ulos may accompany the deceased or be used in related ceremonies, reinforcing the connection between the living and the dead.

Colors, patterns, and motifs in ulos carry layered meanings and can indicate family affiliation, regional origin, or the specific occasion for which the cloth is made. While there are many regional styles, white or light-colored ulos are often associated with purity and blessing, and darker or multicolored designs can signal different social meanings. Variations exist among Batak subgroups such as Toba, Karo, and Simalungun, each with distinct weaving traditions and motifs.

Today, ulos continues to be produced by skilled weavers and remains a potent symbol of Batak identity. Contemporary weavers blend traditional techniques with modern designs, and efforts by cultural organizations support the preservation and transmission of ulos-making knowledge to new generations.
