I subscribe to the thought of buy quality gear and use it. My go-to pack for going deep and steep for extended hunts is still my Longhunter Rendezvous. 7000+ ci, and it collapses well. Sheep, goat, elk, moose, deer, and few lopes have been persuaded to take a ride in it.

It's been used an abused and it still has a lot of life. It handles heavy better than my creaky knees do.

Can't go wrong with quality...Kifaru, Mystery Ranch, and I'm sure there are others.
