“Do I need a chest rig?” You have probably asked this already yourself at some point. I did and I do “need” one. But to be honest, only in terms of weight reduction (in comparison to a plate carrier). Also for the OPFOR roles in most games it is often not allowed to use some kind of plate carrier or body armor with harness, therefore chest rigs are more suitable – and in my opinion a lot more comfortable to wear. Not to forget some other perks.
