Most of mine have been thrown away after being shredded with various calibers through extensive testing.
The ones that are worth a shit are not only too heavy to wear, but don't provide enough cover.
And to provide a high % of body cover would mean really fucking heavy.
Remember, any dipshit with a $150 semiauto .22, a scope and subsonic ammo can manage 3" groups and do a lot more damage if so inclined than your average AR15 wannabe commando since those shots are easily heard and people scatter while with the aforementioned .22 you can quietly go about your business, take breaks, etc, and if you're well hidden you can cause a lot of damage from up to 200m away.
I think it's more important to be aware and prepared than to rely on armor. To me body armor is like speeding while relying on a radar detector.
Sure the chances are reduced, but not enough.
