Backpack armor is a ballistic plate armor that spreads the bullet/sharp weapon’s force impact against piercing through the human body. The ballistic plate can be purchased separately with the bag or you can settle on a wholly sewn bag with the backpack armor.
The backpack armors are different in types according to the National Institute of Justice’s safety level, which verifies and certifies the ballistic plates in terms of quality and durability. The NIJ has authorized and guaranteed only six types of backpack armor that are fit for safety. These are;
• Level 1 – This was the first plate armor to be invented, but its safety level is lower than the others. Hence it is no longer in the armor market and also not recommendable for safety purposes.
• Level 2-A – This is the minimum safety ballistic plate, even though it can shield against 9mm and .40 Smith & Wesson bullet.
• Level IIIA – Protects against all ordinary handgun bullets, slugs strike, and sharp weapons. 357 SIG, 9mm 45acp, up to .44 magnum and 12 gauge.
• Level IIIA+ – This guarantees the safety level of Level IIIA and against ammunitions: 7.62 by 39mm and .223 Remington rounds.
• Level IV – This is the best backpack armor; it can withstand against all sizes of ammunition and piercing handmade weapons.
However, it is essential to note that backpack armor only guarantees temporary protection if you are exposed in any gunfire, an accidental gunshot, or heavy fire rifle before taking cover. Besides, the plates also have a date of expiration, of which after the date it becomes unreliable for your safety purpose. Furthermore, you should avoid keeping it/ exposing the plate armor to extreme temperature and heat because it affects its efficiency.
While purchasing a backpack, armor is useful to confirm if they are certified according to the rules of NIJ safety level for durability and quality purpose.
