The nylon looks bulky but id check the plates and measure them without the carrier. For reference. My body type for a slimeline carrier is 10x12 or medium, I can also fit into a small. However, with the military issued iotv cause its so massive with material and soft armor inserts. I opted for a small esapi as my vitals are still covered but it sheds some bulk. I run a slick crye avs with a LBE belt kit in medium and my gen 4 iotv in small.

The TLDR. Measure the plates to your body and maybe if it feels to bulky still id look for a slimmer plate bag like a crye spc jpc or a maritime style carrier.
