Last summer I picked up a North Face 4800 CI internal frame pack for my daughter. Based on experience backpacking with it, my next hunting pack may not be a "hunting pack."
Meanwhile, I've been pretty happy with an Eberlestock gunslinger. The large main pocket works well for bulky clothing. The rifle scabbard area carries my safety harness, tree stand straps, and pruning pole where I can get to them from the outside. The wrap-over top pocket carries license, light, knife, lunch, etc.
The only things I don't like are 1) like many hunting packs, it is heavy due to the fabric used, and 2) it's too flexible and cushy for packing heavy loads comfortably.
