I have used it for a week of deer hunting, but I was day hunting and not really "backpack hunting" so can't comment too much and only had to carry a deer a 1/4 mile in it.. That said I think Kurt beat out atleast 95% of the hunting pack market with his first ever pack he's brought to market. Pretty damn impressive really. I'm surprised more Mystery Ranch NICE owners aren't giving these a try yet as the straight back profile felt pretty similar to me, but the waist belts rode differently. Overall great packs for sure and I wouldn't hesitate to suggest someone buy them at all in the limited use I had with it.
