I can sum up the Fox plate carrier in 2 words...Chinese junk.
It might be OK for Airsoft, but not real world applications. Brand new (purchased yesterday), and this is what I got.
I'm friends with the seller, so he's gonna make it right...I may have just gotten a lemon, but there is no strike two as far as I'm concerned regarding "gear".
A Condor or USGI plate carrier would be much better than this piece of garbage.
Took a short vid of the problem: https://vid.me/flJK
