Level IIIA body armor vs assorted calibers 9mm through 12ga slug.
Cool pics, crappy site.
Also, from the comments where I found this:
I have a 3a vest, I think everyone should own one. They aren't that much, I paid 500 for mine. For what it can do, I'm surprised more people don't own one. I know a ton of gun owners, but they don't own a vest. I tell them I have one and they say "why would you have that?!". I say "the same reason you'd have a gun, to protect yourself".
Thoughts?
