Kind of expensive, but I have a King of the Mountain wool pack. I cut the waist straps off of it. Has three compartments. Smallest one on the front is where I put my lunch and shooting tab. The deep pocket behind it gets my binos, arm guard, sheath knife, extra hat and face mask, etc. The large main/back compartment I use for extra clothes, survival items, extra flashlight, cord, etc. I hang it from the tree next to me at about waist level and open the front two pockets half way. Can easily retrieve what I need with very little movement.
