My daughter's day pack weighs less than a pound. It's tiny, but held what she needed. Mine probably weighs two pounds.
The issue isn't just weight, though, it's cost. Lightweight hiking gear gets spendy. And bulky. I can be a bit clumsy as is; the bigger my pack gets, the worse that gets, especially the moment I go off-trail.
As for carrying an animal out whole....when I was much younger and a bit dumber, we did it a lot, between two of us - we'd throw it on our shoulders and take turns toting a smaller deer, or lash it to a pole like the old paintings would depict the Indians doing at Thanksgiving. That frankly was terrible. Or we'd just drag it. The doe I keep referring to, I did tote her a quarter mile or so. The weight wasn't terrible, what was terrible was that the weight was off-center. Every step was a balancing act. But once I got her deboned and stuffed into a pack, honestly, it wasn't that bad. With the daypack more or less full and some other random gear lashed to the sides of it I couldn't really sling my rifle and had to carry it alternately port arms or balanced in one hand, but the 1.25 miles I packed her went much faster than the 0.25 miles I carried her.
I didn't get pictures of any of that. I shot her at dark and gutted her, toted her about a quarter mile and knew I was either going to hurt myself or be out there half the night or both, so I dropped her, pulled out my little tarp and knife and headlamp and started deboning her, and the rain started. So I finished that in the rain then packed her out in a light mist. Definitely a 'type 2 fun' sort of night.
ETA: wait, I did get one picture of her. Yes, that’s a 30-06 I walloped her with. She was an older doe. Not sure her weight is obvious in the picture but photography isn’t my strong point.
Per Google earth, she was about 2,830 yards from the truck when I shot her. So 1.6 miles. Fun night.
