The Cabelas frame with pack I have can be used either with or without the pack. In the picture I just had the frame and was using it to carry the last of my animal out of the dark timber where I shot it. The pack can be used with the frame or alone since it has hidden carry straps that come out of the main body if needed. The frame is very light weight and could actually serve to carry any pack regardless of manufacture. The pack I got with mine is quite large and would work wonderfully to pack in for a spike camp. In addition it is mostly waterproof with lots of methods of attachment. The frame even has an orange cover with straps that comes out of a pouch to hold quarters of meat. You put the quarters on the shelf and then pull out the orange cover and tighten the straps to securely hold the quarter. No movement or shifting and the frame sits on your hips to balance the weight.
This is the one I have.
