I'd echo this. I have a gs05 gunslinger, and it is a great daypack, and is capable of carrying out a load, but I wouldn't count on it for multiple long loads. My only other complaint is that there aren't many pockets for organizing gear. I really like the low and narrow profile of the pack on my back, if you can duck it with your shoulders, the pack generally doesn't get hung up. Eberle makes good, durable packs, especially for the money. There are better packs out there, but I like mine for what it is.I have had a J104 for years. The pack is super durable. It will hold anything you can strap on it. I think it is at its best as a daypack that converts to let you take your first load of meat out with you, rather than a backpacking pack. As has been mentioned, though, the load lifters are not functional with heavy loads. This really puts pressure on your back and shoulders. Long, heavy, packouts can be grueling. I have a Kuiu Icon 6000, and the functional load lifters make all the difference in the world. The best feature on Eberlestock packs for riflehunters is the backscabbard. It is the best way to carry a firearm in the field I have used, although I have yet to try the Kifaru gun bearer.
