These fit absolutely perfectly into both my kids elementary school character backpacks. I looked at other options but decided to order from Bulletproof Zone because of their care in making the rounded-top insert. Every other offering online has a tactical look, with squared or blunted corners that looked like (and are clearly for) a vest insert. These are nice quality without the military look.
Both my kids were a little apprehensive about carrying these, but 2 things helped out.
1. The weight of these is barely noticed. Both kids were fussy saying their backpacks were going to be heavier, but at 1 pound- they had forgotten by Monday morning. The unassuming look also blends right into their backpack lining.
2. The topic of school active-threats is scary, but our kids’ school practices drills, and I made the analogy that this is like wearing a seatbelt in the car. You never want to use it- but it’s there “just in case.”
Overall- it’s not much weight, and this won’t offer a large area of protection; but in scary moments, every little bit helps. And it gives us just a tiny bit more peace of mind.
Well worth the cost of the product.
