In certain circumstances, carrying ammunition on the warbelt can be inconvenient (for example, when you are in a car) or wearing a body armor equipped with magazines is uncomfortlable or unnecessary (in hot weather or at a shooting range). Different types of chestrigs were invented to solve these problems.   

"SSO/SPOSN" "Signum" harness vest has many MOLLE webs to place different pouches. From the inside, the vest has 3D mesh pads, the upper part with MOLLE can be folded inward, but when raised it allows you to place a SAPI or Granite plates.   

The vest is functional and lightweight and the strap doesn't interfere with the straps of a backpack which makes it extremely nice to wear. In the bottom there are slings for attaching an RS-40 type belt.
