I'd get the Kifaru Duplex frame. From there, you can get several bags for that same frame. I'm really digging the mountain warrior bag on the duplex frame right now. It's got plenty of room, and I'd do 7 days no problem. I just had it in the bathtub cleaning the blood out of it. I've packed out 8 bucks in the last 2 weeks with it. I'm slowly becoming a pocket slut, for keeping things organized. Not a fan of dumpster diving anymore.
