What’s to stop you from using this with a roll top dry cell, e.g., from stone glacier or sea to summit, as a camp bag to haul in all your gear for a back country hunt, drop the dry cell, collapse the stays, and day hunt from there? My issue with the big frames is that they stick up to my ears, and I never feel like I’m moving freely enough with one of them on my back. So usually I carry in a designated pack for hunting along with my pack out frame. This new system seems to eliminate those concerns, if used along with a dry cell. I guess the question is how much gear can one reasonably place between the bag and frame?
