My hunting is so much different from most of yours that my pack(s) would not apply. They vary by use; place, stand, stalk, airboat/buggie, camp or on my own for a few days.
Always GatorAde or sports drinks, some meal replacements (shake, bars), M&M's, small binoc's, ammo reload, orange vest, small bug spray, vinyl gloves, SuperGlue, 100' 1/8" braided nylon line, a handfull of 14" tywraps, cheapie Coleman poncho and blanket.
On person; Swiss Army knife, game knife, machete, rifle or shotgun, pistol & xtra clip, Zippo and waterproof matches, SS signal mirror, low light glasses, small bug spray, folding money, ID (license, DL), camo makeup kit, mini bang stick.
