Vietnamese conical hats, known as nón lá, are traditionally made from palm leaves, bamboo, and moc tree bark. The leaves are carefully dried, ironed, and stitched onto a bamboo frame to create the hat’s iconic shape, providing both sun and rain protection.

The price of a nón lá varies depending on the craftsmanship and materials. Simple versions cost around $2–$5, while high-quality or decorative ones, such as those from Hue with poetic inscriptions (nón bài thơ), can cost $10–$30 or more.

The most famous place for making Vietnamese conical hats is Hue, particularly in villages like Phu Cam and Tay Ho, where artisans handcraft nón bài thơ—hats with hidden poetry or images embedded in the layers. Other well-known hat-making villages include Chuong Village near Hanoi.

The traditional hat in Vietnam is called nón lá, which translates to "leaf hat." It is worn by farmers, laborers, and even fashionably by women in ao dai dresses. It symbolizes grace, resilience, and Vietnamese heritage.
