What do I need, to put side plates on my plate carrier vest?

[5Heathens]

I recently acquired this plate carrier, unfortunately there is no slot for side plates. What do I need to get in order to have side plates on my vest? Thank you

Which vest is that? It doesn’t look like that one accommodates side plates. Normally your vest will have spots for front back and side to put your plates in. Which plates is another topic.

Cummerbund with armor pockets.

On second viewing...

Get a different plate carrier. That front opening is problematic.

That looks like a generic soft vest (Lvl III?) that can maybe take extra trauma plates
