How much room do you have available in your plate carrier. Our thinnest plate would be the steel Level III+, as they are only about 8mm-10mm thick.
I'm not sure exactly. When the carrier is laying flat on the counter, it looks like I could fit something close to an inch thick, but when I put it on, it doesn't feel like I could put anything thicker than 10mm in it... Do you guys have plates without the foam that aren't steel?
