Blunt trauma personal protective equipment (PPE) protects the wearer against injuries caused by blunt impacts. For law enforcement, corrections, military, and other personnel involved in emergency response operations, the protection against blunt impact threats can be a matter of life or death. To quantify the levels of protection of a Blunt Trauma PPE, users and industry rely on technical standards. A balance between protection and functionality allow users to have good flexibility and mobility. Good air ventilation underneath the PPE suit can protect users against heat stroke or hyperthermia.
