BACKPACK simple harness TWO POCKET. The harness is for short haul, brief periods of carry. The two pocket modular component for the main compartment fits on front. The main compartment (padded with hollow core plastic frame construction) can be oriented either vertically or horizontally, to best fit the camera equipment that you own and the divider planks keep things neatly organized. A large soft camera bag is included, too. For additional modular cases see: (BK-LPM) Front LAPTOP POCKET module, (BK-RBM) Removable BELT module, (BK-TQM) Tripod quiver module.
