Depends on your budget. For under $400 I would look at finding a used Dana designs frame, or an Eberlestock. Right now Kuiu has their icon 7200 packs on clearance for $399. For $4-600 I would look at Mystery ranch and over $600 gets you into the Kifaru/stone glacier tier of packs. Get the best pack you can afford and make it work. I'd be more concerned about a 10 mile hike in august with spoiling bear meat
Kifaru, Stone Glacier, the Exo looks good as well.
