Loves2Hunt - Check out the Monster Fanny from Badlands. It should be all you're looking for!
terjeness - Both the Eberlestock and the Outdoorsmans will allow you to haul in your gear and pack out your meat. Due to the rigid structure of each, neither will convert to a "nice little day pack" so you will need to decide what is most important. They are both fairly lightweight and have straps that allow them to compress. Having used both, here's my opinions:
Eberlestock J107: Allows for huge expansion with purchase of exterior duffles, integral gun scabbard can also be used for your tripod, many pockets, hydration compatible, removable top pocket that turns into a very comfortable fanny pack, aluminum stays for structure, plenty of height adjustments on shoulder harness.
Outdoorsmans: the most innovative, superior hunting frame ever built, combines the comfort of an internal frame with the load handling of an external frame, plenty of pockets designed to handle spotting scopes, tripods, and other gear, hydration compatible, gun/bow carrying system, easily adjustable for height, bag can be quickly removed from the frame that includes a meat-carrying system.
Best thing about Badlands, Eberlestock, and Outdoorsmans packs? The Outdoorsmans carries them all! Give them a call at 800-291-8065.
