lol, for that you need hard armour plates and/or soft
armour.
none of these vests are even soft armour so you dont get any
protection.
they all look like asian copies of real deal.
real deal often costs hundreds-to-thousands of dollars.
the blackhawk down vest is a copy of the vest made by pt
industries, who, iirc, went out of business many years ago.
check out these real deal companies, for a price guide on the real
stuff:

[sds are official us suppliers]
and the well known cheaper-brand - blackhawk industries [famous for
making copies, and then having to open a factory in the us because
if they didnt, us customers wouldnt buy from them because their
main factories were in vietnam and so were not 'american
made'].
