One of the great things about Spiritus Systems is the modularity of their gear.  If you have a need for additional storage on your back, there are several options to choose from.  The OVERT Rear plate carrier has a zip on attachment that is compatible with the MOLLE Back Panel, the Assault Back Panel Core.  The Delta bag is a stand alone backpack.  Note: The Assault Back Panel is a specialized piece and has three different top panel attachments.
