The Unaweep is an integrated backpack model. You can swap different integrated bags with the frame (like the Gila for example) but there is no load shelf between the frame and the bag
I have the same pack and was wondering what the value of it is. I have what you show, plus the Talon and additional pack that goes on top of the bag. I love my pack, but thinking of selling and upgrading but didn't know the value.
The buyer of this pack is going to love it!
