It is said that the prototype of the coat commonly known as the "pea coat" existed in the 18th century. The name is an English version of the Dutch word "Piijekker," where "Pii" comes from coarse woolen material and "jekker" from jacket. Pea coat-type coats have been adopted by some militaries in European countries, but this pea coat is from the 1910s, when it was adopted by the U.S. Navy as a coat for non-commissioned officers. The pea coat of the 1910s was characterized by its use of thick, high-density melton wool material and by its anchor buttons engraved with 13 stars representing the coat of arms of the United States. The 13 stars originate from the fact that the United States had 13 states when it became independent in 1777. The exact time when the U.S. Navy adopted the pea coat is unknown, but the overcoat was already listed as a coat for noncommissioned officers in the dress code of World War I. The large collar is designed so that when working at sea, the collar can be raised to cover the face and provide sufficient protection against strong winds. There are also vertical slit pockets, which are hand warmer pockets to warm your frozen hands. From the 1930s onward, productivity and costs were reviewed, fabrics became lighter, and the 13-star button was abolished.
The length of this peacoat is slightly shorter than that of the government-issued one to give it more mobility, and the edges of the pockets are made of leather for strength.
