Hat: Pith Helmet

A lightweight helmet, made of cork (originally sola pith) covered with white cloth.

The Pith Helmet was used by all European armies, by troops deployed in tropical locales.

The Pith Helmet was the common headgear of the tropical tourist.

Until the 1930s, it was believed to be required, in order for people of European descent to avoid sunstroke, while in the tropics.
