This photo shows our bulletproof vest with an 8 x 10 armor plate being installed. You can see from the size of the pocket that our vest will hold up to a 10 x 12 plate securely.
Our vest has two pockets, one for the front and one for the rear. You'll have no trouble upgrading our vest from class IIIA to class III or class IV protection using readily available body armor. Most people don't need protection from rifle fire and don't wanted the added weight of armor plating.
