What is french wwi helmet?

The French WWI helmet, officially known as the Adrian helmet after its designer August-Louis Adrian, was the standard helmet used by the French Army during World War I. It was also used by several other countries, including Belgium, Greece, and Serbia.

The helmet consisted of an iron shell with an inner leather suspension system to prevent direct contact between the head and the helmet. It had a distinct crest on the top, as well as ventilation holes on the sides. The helmet's design was meant to protect soldiers from shrapnel and head injuries from falling debris.

The Adrian helmet became an iconic symbol of World War I and remained in use by the French military until the 1960s. Its design influenced the development of other helmets, including the British Brodie helmet and the American M1917 helmet. Today, the Adrian helmet is still sought after by collectors and enthusiasts as a piece of military history.
