What is a "pith helmet"?

A pith helmet, also known as a safari helmet, is a type of headgear made of lightweight material such as a pith or cork. It typically features a high domed crown and a wide brim to provide shade from the sun. The pith helmet was originally developed in the 19th century as military headgear for soldiers serving in hot and humid climates. However, it later became popular among explorers, hunters, and travelers as it was practical, comfortable, and provided protection against the sun. The pith helmet has a unique appearance that is recognizable and is still used in some countries today, particularly in Africa and Asia.
