The main compartment, which is closed with a drawstring, is positioned beneath a flap which has a magnetic clasp. On the inside of the main compartment there is a zip compartment. The backpack has two mounted front pockets, along with larger side pockets fitted on both the right and left hand side; the flaps for the pockets are secured in place by a magnetic clasp. A special feature of this bag are the dual D rings, to help with attaching small bags such as, e.g. the bag model HF-0011. The base is reinforced with leather strips and metal stoppers. The shoulder straps are length-adjustable. There is an additional zip compartment located beneath the back shoulder straps.
