A (called a or when worn by men) is a protective headdress made and typically worn by Ivatan women of the Philippine Batanes and Babuyan Islands. It is woven from strands of abacá and vuyavuy palm fiber, and is designed to shield the wearer from excessive sun, wind, and rain. It can also serve as a mat for babies or as a pillow for farmers resting in their fields. The headgear consists of a hood going around the head and a cape down the back.
To make , collected vuyavuy leaves are first shredded with a metal brush, leaving the leaf's central rachis (central spine) intact, and then hung to air-dry for three days before being cut lengthwise along the rachis. Higher-quality have a strip of abacá banana leaf string (made by quickly rolling abacá fiber between one's palm and leg) wrapped around the rachis. This makes the headdress more comfortable on the skin. Approximately fifty of these half-fronds are laid out overlapping in horizontal rows, which are then fastened together from top to bottom using plastic or abacá string. Each row of leaves is bound at the edges of the cape to abacá fiber. The fibers around the head are then trimmed above eye level. The hood is made waterproof by two pieces of abacá stem tissue covering the central eye of the hood. The headdress is then hung to air-dry for three days, during which it goes from green to straw-yellow. made entirely from abacá are called .
