Are you packing out meat or just packing in lunch and clothing?
I don't know how large those garments are but maybe you don't need a pack with a belt ... for bulky but light loads, I like a Badlands Pursuit or 5.11 Tactical Rush 24.
If you are also packing meat out, then I'm liking the Eberlestock F1 mainframe and a bag .. their Vapor 2500 would be a good sized choice.
