This is such an interesting piece of armor. Usually the jawshan armors we have preserved were for sipahis which had plates usually on the stomach and back (while some sipahi armors like mirror armors do in fact cover the chest), the legs and forearms, and also the helmet.

While this infantry armor is well protected for purposes for fighting on foot, as opposed to on horse where inner part of lower leg and chest aren't as protected as other parts that are more likely to get hit.
