HISTORY In the beginning, there were injuries. From cycling's earliest days there were head injuries. As more roads were paved it is likely that the head injuries increased, since macadam and asphalt are completely unforgiving as crash surfaces. In the 1880's high-wheel users in clubs saw that head injuries were a problem and began using pith helmets. Pith is a crushable material, and was likely the best material available at the time. Although it would probably break up on impact, there were few cars on the roads, so riders needed protection only against a single impact. Around the turn of the century racing cyclists began using "helmets" made of strips of leather-covered padding, initially with a ring of leather around the head and a wool ring above that. Then the style evolved and the ring of leather around the head was supplemented by strips of leather arranged longitudinally on the head. When I started racing in the 70's we called them "hairnets" and the nicest ones were made in Italy of beautiful soft leather.
INTRODUCTION A helmet is a form of protective gear worn to protect the head from injuries. Ceremonial or symbolic helmets (e.g., UK policeman's helmet) without protective function are sometimes used. The oldest known use of helmets was by Assyrian soldiers in 900BC, who wore thick leather or bronze helmets to protect the head from blunt object and sword blows and arrow strikes in combat. Soldiers still wear helmets, now often made from lightweight plastic materials.
