Not that I am aware of, which bolsters my point. If airsoft pellets keep ripping through everybody's "bulletproof" vests and they all keep telling you to have faith in their new vest, and no, they will not provide you any evidence that it works, then any sane person would be running for the hills. You should be completely skeptical that an entire industry that can not even stop airsoft pellets can suddenly able to stop bullets, 354th times the charm for sure, until they show you some extraordinary evidence. Fool me once, shame on you. Fool me 354 times in a row for three decades, shame on me.
