The bulletproof helmet is a protective device used to prevent the penetration of projectiles or fragments, effectively protecting the human head, but not affecting the human eyesight and tactical activities. According to statistics, in the classic battle of the 20th century, 75%-80% of fatal injuries were caused by fragments of mines, grenades, etc.; and 45% of these injuries were in the head. The British authorities have also shown that wearing bulletproof helmets can reduce the injury rate by 5% and the death rate of 19%.

The second stage: non-metallic bullet-proof helmets, mainly Aramid material helmet; The world well-know "Kevlar Bulletproof helmet" is one of Aramid helmets. There is a saying in China" all Kevlar helmet is ballistic helmet, but not all ballistic helmet is Kevlar helmet.

In our next topic, when we discuss with you about Aramid and PE bulletproof helmet trends in the future, we will tell the main difference of Aramid helmet and PE Helmet.
In the end, we show you some photos of ballistic helmet. Present helmet, mainly NIJ IIIA Level, resist 9mm and .44Mag. In recent years, some China Body Armor factories developed a new helmet, which can resist AK47, but it is too heavy, about 4kg/pic, and production cost too high, most users can not afford Or accept it. We hope in the future, China factories can invest more,make AK47 helmet lighter and lighter, the bulk production cost lower and lower.
