A helmet is not a piece of gear which is required for everyday use, but they are much-needed for ballistic protection in a bad to worst-case situation, e.g., a patrol officer or military person rolling up on a potential shooting. In that situation you would hope your head to be covered behind cover that can provide protection with that covering.
Kevlar® helmets are one of the oldest forms of personal protective equipment and are known to have been worn by various Law and Enforcement people for their protection. Kevlar® is one of the high quality ballistic material that offers improved protection and it’s used for making helmets as well. Kevlar® helmets has resulted in improved protection ,less weight of the helmets and protection against head injuries caused by blasts. They also help in offering protection against a wide range of threats, including submachine-gun bullets and fragments.
Since Kevlar® is just a material so ballistic helmets come in various designs like PASGT( Personnel Armor System for Ground Troops) , MICH (Modular Integrated Communications Helmet ) S.F. (Special Forces Type Helmet) and various sizes with additional accessories like: Night Vision Device, Picatinny rail etc. Rigorous impact testing shows military helmets made with Kevlar® fiber have superior structural integrity to help enhance survivability in ballistic and non-ballistic impact.
In order to conclude we would like to suggest that you have two eyes, two arms, two legs, and two lungs – but only one brain, so we should keep it safe by providing the best protection.
