One of my things with a daypack is that I want to carry a quarter on my way out from a kill. I carried a Nimrod lumbar pack that has a packsack that attaches to the shoulder straps to use as a meat bag for a number of years and carried five or six quarters with it. It worked, but was very uncomfortable with a quarter. It was great for hunting, out of the way and quiet. Last year I got an Eberlestock J-105. Much heavier, still pretty quiet. I carried three quarters with it, but only for a short, steep carry. It seemed pretty comfortable to me. 2 more cents.
