[KeiraMarie]

The lightest flip-up helmet weighs approximately 1330g. Function of helmets: Helmets are protective gear designed to safeguard the head. They are essential headwear for military training and combat operations, as well as indispensable tools in transportation. Typically semi-circular in shape, helmets mainly consist of three parts: the outer shell, inner lining, and suspension system. Helmet construction: The helmet shell is made from high-strength materials such as metal, engineering plastics, or Kevlar fibers, which absorb most impact forces through deformation. The lining material functions to absorb sweat, provide warmth, and offer shock absorption. Military helmets often feature additional capabilities to further mitigate impact forces and prevent injuries from shell fragments. The suspension system, located between the shell and the inner lining, is usually adjustable to accommodate different wearers' head shapes.
