Generally, bulletproof vests can only provide level IIIA bulletproof protection, which is enough for handgun bullets, but not so for rifle bullets. In order to improve your safety-level in dangerous areas, our level 4 ballistic plate, which is made of aluminum oxide ceramics and is 23mm thick, can provide level IV ballistic protection. The ballistic plate can not only resist handgun bullets but also rifle bullets. The light weight of 2.95 kg will not influence your movement speed.
