Level IIIA resists penetration from .357 SIG, 9 mm, and .44 magnum. Those are handgun rounds. It may stop some intermediate rounds if you’re lucky, but certainly not full power rifle rounds. Helmets cannot deform as much as vests before seriously injuring the wearer, limiting their capacity to dissipate kinetic energy. And if you make them too rigid, concussion becomes a problem. |
