ALPS OutdoorZ Pack Bag for Commander

Cabela's says:
The Alps OutdoorZ Pack Bag fits the Commander pack frame, upgrading it to a meat- and gear-hauling beast that's suitable for the toughest of backcountry pursuits. Nylon-ripstop construction stands up to brush and rough handling, while an integrated rifle holder frees your hands for balance when hiking into camp. Easy-to-access top-loading design features a spindrift collar with a drawcord closure to secure contents. Two hinged side pockets, main pocket, front pocket and spotting-scope pocket offer ample room for all your gear. Zip-close lower access lets you grab items from the bottom of the pack without dumping the entire bag. Hydration pouch and port offer compatibility with your favorite reservoir. Internal horizontal divider makes organization easy. Webbing loops let you lash extra items on board. Clevis-pin attachment. Imported.
