Most "bullet-proof" vests only protect against relatively weak, slow, large handgun rounds (9mm, 40 cal, .44, etc.). High-power rifle rounds used for hunting (.223, .308, 30-06, etc.) would easily penetrate this material. I only mention this because, when you talk about something being "bullet-proof" you need to understand, that's not true for most rifle rounds, only handgun rounds. And if parents buy this material, they need a clear understanding of what it does stop and what it does not stop.
