I currently have a Mayflower low-profile carrier, along with a chest rig I can attach to it, with some soft armor and some plates in it (of which I don't actually recall the make or model at the moment). I purchased that carrier and developed that setup specifically because it does a lot in terms of allowing me to wear the armor without plates pretty easily concealed, with plates somewhat easily concealed, and with load-carriage on the outside when I want it.
I'm thinking of upgrading the whole thing because (a) I'm guessing there might be newer options, (b) I'm just curious and (c) the setup was always a little tight and now is a little tighter (d) it's not the fastest thing to get on and I might think about having two separate setups, one with just the soft armor and one a combo plates/mags.
This is essentially what I have now, but mine is tan.
This is what it looks like "jocked up", although I also have a three-mag solution without the BOK.
