I know there’s been tons of replies. I’ll keep mine short. I owned the following. Wanted to try the Kifaru but didtnt get good vibes from some of their staff so I’ve passed on ever trying them.
At least the 2017 models. EXO, Mystery Ranch and Stone Glacier. For me they go like this in this order. And I still have all of them.
EXO 5500
Stone Glacier Talus 6900
Mystery Ranch Metcalf
EXO. Has every damn feature in a Crazy light package. Way more thought went into this pack than all the others. So many little features that the others over looked. The way the lid sits and fits, the pocket design and so on. Hip pouches are the BEST! With the pack empty, it’s very comfortable. Bends and twist with you. So comfortable! When it’s loaded, it packs weight every bit as good as the rest, except the Stone Glacier might have a very slight advantage when getting over 100lbs. Way too much to go into on the EXO. Comfortable empty or loaded is why is comes out on top, and so feature rich. Just so so much into this packs design. Wish the belt had quick release tabs to loosen though. Excellent customer service.
Stone Glacier. Probably the king of them all when it’s time to pack over 100 lbs. But other than that, not a whole lot more going on with this pack. It lacks a lot of features, pockets, etc unless you get the 6900. Frame empty feels almost like a piece of plywood. Not bad, just noticeable. Still built very well as are the rest, just needs more thought put into pockets, Layout, meatshelve straps, lid, etc. But loaded is a gem to use. No question it’s the best at packing weight. And the frame and bag are tough as well. Stout buckles as well, decently designed meat shelf. Great side pouches as well. Customer service is excellent.
Mystery Ranch Metcalf. Prob best customer service. I’ll Just say that. The pack and frame just kinda sit around the run of the mill as far as features and comfort. Frame twist and moves very well, almost don’t even realize it has a frame. Bag is nice and their buckles (what they are famous for ) can’t be beat. The bag has a few pockets, excellent lid and love the load shelve. In my opinion, it has the best load shelf. Where this pack lacks is the waist belt. It’s way too narrow and can put a lot of pressure on parts of your hips. Needs another inch in width. The lid also sits kinda awkwardly at times. Also needs bigger external pockets. This pack has the worst side pouches. Flimsy to say the least and when you unbuckle the belt, the pouches slide all around. Loaded with 100lbs or less, it’s very comfortable and does the job but would benefit with a wider waist belt.
Just my .2 and opinion
