When you purchase a ballistic vest, you do not buy one size to fit everyone. AoA believes the same should be true with hard armour inserts.
Ballistic vests are available in small, medium, large and extra large sizes.
All are curved panels Hard armour inserts produced by AoA all feature ceramic faced impact surface. Rigid support of the ceramic surfaces is accomplished by one of several proprietary AoA fiber laminates. No hard armour inserts manufactured by AoA uses ferrous or non-ferrous metals. The use of such material in hard armour inserts, which are designed to protect the chest and back of the individual, can be dangerous. Projectiles impacting metal will either produce excessive small fragments or ricochet.
