pith helmet
A lightweight cloth-covered helmet made of cork or pith. 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. The gear is seen as typical explorer's headwear, and thus will be associated with those exploring wilderness (such as a safari) or going on expeditions.
