I got a Just One pack last year and am very happy with it. I thought it carried so well that I didn't even bother swapping out for an external pack frame on the 2nd trip, just used my J34 on the 2nd trip as well.

Here's my elk cut up and ready to pack out.



I posted this on another site and someone pointed out that it would probably be better to use clear garbage sacks for the loose meat because some of the colored sacks have anti-fungal stuff in the plastic. Seems like a good tip and I'll probably be switching to some clear sacks for next year.

Here's the first trip out. I had one front shoulder in the pack, plus what I started with and of course the head.


Here's the 2nd trip out. I had one deboned hind quarter in there and a front shoulder. I had emptied my pack out of everything but the neccessities for this trip.


Here's my New Mexico elk quartered up and hanging in the tree. We packed out the head and cape and the loose meat (backstraps, tenderloins, neck meat) on the first trip and actually paid some guys on horses to pack the quaters out the next day.

I'm going to add a pulley to my pack for the future so I can get the quarters higher up in the tree next time. It worked this time, but a big bear could have gotten to them as they were only 8' or so off the ground.



Here's the head and cape going out on my back.


I personally use the Alaskan game bags and think they do a great job. I've even reused them a few times with no issues. After using them 3 times this year they were pretty worn though so I bought new ones. Don't get the deer sized ones, those aren't very sturdy, get the ones specifically for the quarters.

I really like my Eberlestock J34 pack. Really nice carrying your rifle in on your back when you are bushwhacking in several miles in the dark every morning.
