A pith helmet is a lightweight, protective headgear traditionally made from the pith of the coriander plant or other materials like cork or fiberglass. It is designed to shield the wearer from the sun and is commonly associated with explorers, adventurers, and colonial-era figures in Africa and Asia. The helmet's wide brim provides shade and helps keep the head cool in hot climates. Originally popularized in the 19th century, the pith helmet became a symbol of colonial expeditions and military campaigns. Today, it is often worn for outdoor activities such as hiking, safari tours, and gardening, offering both style and sun protection.
