What type of hat is characterized as a wide-brimmed travel hat?

The petasus is a specific type of hat that is recognized for its wide brim, designed primarily for travel and outdoor use in ancient Rome and Greece. Its broad brim served a practical purpose: it offered protection from the sun and rain, making it particularly suitable for travelers who spent prolonged periods outdoors. The made of felt or straw, it was lightweight and easy to carry, fitting the needs of those on journeys.

In contrast, a stola is a garment worn by Roman women, the zona refers to a belt or girdle, and a paenula is a type of cloak or outer garment, which does not share the characteristics of a hat. The petasus stands out among these items for its specific design as a hat, fulfilling the role of providing comfort and protection during travel.
