This backpack comes with our generic shoulder straps and a detachable two pocket module. The harness is for short haul, brief periods of carry, the harness can be upgraded to the AH-3H-MEMS extreme hardness. 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 stuff sack is included, too. For additional modular cases see: (BK-LPM) Front Laptop Pocket Module, (BK-RBM) Removable Battery Module, (BK-TQM) Tripod Quiver Module.
