Terai hat

The Terai hat is a type of slouch hat associated with the Gurkhas and named after the Terai region in Nepal.

[1] It is created by fusing two hats into one to make the hat more rigid and is worn at an angle, tilted to the right.

[2] The double Terai is a version with a double thickness crown and brim, designed to give extra sun protection.

[3] This hat was almost de rigueur in East and Central Africa from the 1930s to 1950s.

[4][5] In European use during the British Raj in India, the sola topi might be replaced with the felt Terai hat in the hills or during the cool season.
