Helmet
A helmet is a form of
protective gear worn on the
head. Traditionally, helmets have been made of
metal. In recent decades helmets made from
resin or
plastic and typically reinforced with
Aramid fiber (e.g.
Twaron or
Kevlar) have become preferred for most applications. Designed for protection of the head in combat, or in civilian life, from sports injuries, falling objects or high-speed collisions.
