The Commander X + Pack is a complete system for the multi-day backcountry hunter. The combination of an internal frame meat hauling pack with a detachable 4000 cu in pack bag offers the ability to pack in gear to a spike camp and haul out meat when the task is completed. The Commander X frame has a lashing system that incorporates a compressed wing system and a lower shelf to secure loads to the frame. The pack bag can then be reattached with a series of compression straps over the load. When the meat-hauling frame is not needed the pack bag attaches to the frame with zippers for a secure fit to the frame for a comfortable carry. The frame is comprised of dual aluminum stays with a channeled high-density ABS frame for rigid carry. Check out the review from Sportsmans News 9994710 Coyote Brown 9994200 REALTREE EXCAPE(R)
