Our level IIIa hard inserts are great to use as back pack ballistic protection as it weighs no more than a school book. Other companies sell backpack armor with light weight soft armor. They sew or place the armor against the front wall of the back pack which will rest on the back of the child or adult wearing it.
Think about the deformation of the soft armor of up to 1 plus inches into the person's back. This trauma would be devastating to anyone wearing it. It could potentially kill a child.
Our hard armor offers the same level of protection with minimal deformation or penetration thus offering true protection to the carrier.
A preferred way to carry backpack armor (hard or soft) is to place the panel on the outer wall of the main pocket of the backpack. Any deformation would be absorbed by the contents of the pocket and not your body.
