Probably the most successful copy of the JPC 2.0 (Jumpable plate carrier) vest
it has a number of goodies, such as a front velcro panel for attaching different types of platforms, adjustable side straps with an elastic band on the back of the vest.
Both shoulder straps have a quick release system using a pull located inside the shoulder padding. The back plate has zippers sewn on the sides for attaching the back panels.
