Ballistic helmets, also known as bulletproof helmets or tactical helmets, are designed to protect the wearer's head from bullets, blunt force impacts, shrapnel and other threats. They are made of Kevlar material, which can reach the highest NIJ IV bulletproof level.
Bulletproof helmets have been used in warfare and combat as early as the 23rd century BC. Since then, countless innovations and redesigns have improved their effectiveness, resulting in the ballistic helmet we know today. They are widely used by military, police and civilians.
