The fiber helmet was originally designed by Jesse Hawley in the early 1930s.
 Hawley subsequently designed the first fiber helmet liner for the original M1 steel helmet, alongside the General Fibre Company, a subsidiary of the International Hat Company.
 The first patent for the Hawley pressed fiber sun helmet was petitioned to the US government in 1935 and subsequently granted in 1938.

The International Hat Company was the first manufacturer of the World War II model of fiber helmets for the US Army, beginning in June 1940 to 1946.
The US Army began ordering the World War II model of fiber helmets from Hawley Products in January 1941 to June 1942.
 During their respective production times, Hawley Products created 27,751 fiber helmets for the Army, whereas International Hat generated 27,434.
The helmet eventually replaced the traditional but more expensive felt campaign hat.

In 1941, the US Marines ordered 44,000 waterproof, khaki fiber helmets to be made of 124 warp and 54 filling of threads per inch, with a maximum weight per square yard of 6 ounces.
The helmet was first issued to the First Marine Division during their 1941 deployment to Guantanamo Bay, Cuba International Hat produced 20,000 Marine fiber helmets for $1.35 each, while Hawley Products produced 24,000 Marine fiber helmets at a cost of $1.36 each.
 In December 1942, the Marine quartermaster ordered an additional 100,000 fiber helmets.
 This included 50,000 to the Depot Quartermaster of San Francisco, 25,000 to the Clothing Officer of San Diego, and 25,000 to the Depot Quartermaster of Philadelphia.
