The pith helmet (also known as the safari helmet, sun helmet, topee, sola topee, salacot or topi) is a lightweight cloth-covered helmet made of cork or pith, typically pith from the sola, Aeschynomene aspera, an Indian swamp plant, or A. paludosa, or a similar plant. Designed to shade the wearer's head and face from the sun, pith helmets were often worn by people of European origin in the tropics, but have also been used in other contexts.
