This is only a draft idea, but can’t contain it. Many similiar solutions already exist – Crye’s StKSS, Mystery Ranch BASE, Virtus system element, BCB load carriage yoke, TYR’s X-frame, TUR Gear PkDLCS. My idea is to make a drop-in addition to any COTS plate carrier and barely any warbelt to add a new feature.
Frame is installed into the PC in the way as danglers, hangers and lower asserory pouches are installed, and sits in the plate pocket. To the warbelt it can be connected via PALs or as drop-leg panels, with thw slots on the w.b., not sure, may be even both types for more stability.
Frame sits on the sides of warbelt, not on the back – for more freedom of movement.
