I carry a Fanny Pack with, Shoulder support straps, inside, my 45 Pound Pack. We hike "in" a couple of Miles to our "Spot" then, we unload the Packs and set up Camp. I put my Fanny Pack on to Hunt with. The FP has,.. 30 Oz's of, water, elk Sacks, Knife, Para Cord, snacks, range finder, call, Rain coat, Emergency stuff, etc and weigh's, very little ! I / we shoot 3 D with these Packs on, quite often and have, NO problem with, GOOD accuracy. My son and grandson hunt with their full sized, EXO packs but, they have, ONLY the SAME stuff in them that I carry, Theirs probably weigh, less than 10-12 pounds total of, Pack, gear & water. We quarter the Elk and make a couple of trips out to the Truck, one with the Gear, one with, the Elk meat. The 3 of us, can take an Elk out, in ONE Trip. Fortunately, it's ALL, down Hill,.. LOL ! PS; Hunting and trying to shoot with, a 50 pound pack "on" is NOT, my idea of,.."Fun"
