One somewhat forgotten sun helmet pattern was that used by the Philippine Commonwealth Army. Issued just months before America’s entry into the Second World War, these seemed based on the pressed fiber helmets used by the United States but offered a larger rear brim. And instead of pressed fiber these were made of pressed coconut fiber!
Reportedly used an a substitute for the campaign or “Montana Peak” hat, these were widely used during the Japanese invasion of the Philippines.
