What is "chullo"

n. A type of hat from Peru or Bolivia, usually made from wool or a similar fabric.

Chullo (, from ) is an Andean style of hat with earflaps, made from vicuña, alpaca, llama or sheep's wool. Alpaca has wool-like qualities that help to insulate its wearer from the harsh elements in the Andean Mountain region. Chullos often have ear-flaps that can be tied under the chin, to further warm the wearer's head.

Chullos have been used in the Andean Mountain region by indigenous peoples for thousands of years. Wearing different types and colors has a significance among the Andean natives.
