This is a genuine USMC-issued APB03 Assault Pack, part of the ILBE (Improved Load Bearing Equipment) system used by the United States Marine Corps. Designed by Arc'teryx and manufactured by Propper International, this pack was built for rugged field use with a compact profile and modular compatibility.
The APB03 is constructed from durable 100% nylon in MARPAT woodland digital camouflage, offering water resistance and long-term reliability in the field. Its main compartment features a clamshell zippered opening for easy access, while an internal hydration sleeve with a top port allows seamless integration with a bladder system.
 
For carrying comfort, the pack includes fully padded shoulder straps, a sternum strap, and a reinforced top carry handle. The exterior is outfitted with MOLLE/PALS webbing on the front and sides for attaching pouches and accessories, as well as dual side compression straps to secure the load. Whether you're using it standalone or attaching it to a larger ruck, the APB03 is a versatile, mission-ready solution.
