SW,
I have the same frame pack, couple of em in the family. Id like to get a new one but just can't justify it cause I have no issues with it. My comments are mainly from archery/muzzleloader timeframe here in Colorado. I either do two things based on the terrain, who else is hunting that day. Scenario one is I have a tag in hand so I usually stash

my frame pack in the woods, central location a few miles in. I put it under a tree with a garbage bag over it and brush it over. I'll hunt then with a fanny pack on that I just strap to my frame pack when carrying both.
Scenario two is I have no tag in hand and I'll put the gear in two small/med dry sacks. The ones that are quiet and scrunch down really small and tight. I'll tie them in with the paracord on the shelf. Depending on the cover/trees I've taken off the top part of the frame so it doesn't stick above my head.
Late season or "open area" hunts I'll do the same with the gear and leave that top frame in place. 4th season cow hunt pic attached.
