This is the Main Bag component of what is officially known as the FILBE Pack or Marine Corps Pack System. Intended to be combined with a matching frame, shoulder harness assembly and hip belt. Together they make the complete backpack used by Marines to haul up to an incredible 125 lbs. of gear in the field. Our last buy of FILBE Packs were all separated out by component, so now you have a chance to buy each part separately.
