I've seen the tests on Myth busters. The last test was placing
the armor over a live grenade, and not a scratch. I was wholeheartedly impressed.

When the prices come down a couple thousand I'll buy a vest for myself.

"I've seen the tests on Myth busters. The last test was placing the armor over a live grenade, and not a scratch. I was wholeheartedly impressed."

To be a realistic test, the armor would need to be pressed firmly against the grenade with about 200 pounds of weight—"supported", like a "supported gunshot wound" is, in forensic ballistics.
