The pith helmet, also known as the safari helmet, salacot, sola topee, sun helmet, topee, and topi is a lightweight cloth-covered helmet made of sholapith. The pith helmet originates from the Spanish military adaptation of the native salakot headgear of the Philippines.
It was often worn by European travellers and explorers in the varying climates found in Southeast Asia, Africa, and the tropics, but it was also used in many other contexts. It was routinely issued to European military personnel serving overseas in hot climates from the mid-nineteenth to the mid-twentieth century.
Typically, a pith helmet derives from either the sola plant, Aeschynomene aspera, an Indian swamp plant, or from Aeschynomene paludosa. In the narrow definition, a pith helmet is technically a type of sun helmet made out of pith material. However, the pith helmet may more broadly refer to the particular style of helmet. In this case, a pith helmet can be made out of cork, fibrous, or similar material. It was designed to shade the wearer's head and face from the sun.

The origin of the pith helmet is the traditional Filipino headgear known as the salakot (Spanish salacot, a term still also used for pith helmets). They are usually dome-shaped or cone-shaped and can range in size from having very wide brims to being almost helmet-like. The tip of the crown commonly has a spiked or knobbed finial made of metal or wood. It is held in place by an inner headband and a chin strap. These were originally made from various lightweight materials like woven bamboo, rattan, and bottle gourd; sometimes inlaid with precious metals, coated with water-proof resin, or covered in cloth.
Salacots were used by native Filipino auxiliaries in the Spanish colonial military as protection against the sun and rain during campaigns. They were adopted fully by both native and Spanish troops in the Philippines by the early 18th century. The military versions were commonly cloth-covered and gradually took on the shape of the Spanish cabasset or morion.
