OK, so I after a couple days use on the incline trainer, here's some first impressions. A few caveats to begin with. This is my fist Kifaru pack, so I'm not fluent in Kifaru speak, nomenclature, etc. These are fist impressions after a couple hours on an incline trainer with the pack loaded up with gear for a 1 to 2 backpacking trip, so 30-40 pounds max. I'm just trying to get things adjusted right now and get familiar with the pack so I can give it a fair representation and use it to its full potential. This will be an incremental thread. So here we go. This is a burly pack and it is evident that it is designed to be bombproof and functional. The amount of straps and the size and bulk of the buckles and other hardware are very noticeable if not a little surprising. This is not a bad thing. Some things we just can't have fail, so I can appreciate the thought that went into the straps and buckles (generalized term) and I'm glad they are that way. I'm on board with the auto locks on the buckles as well, but they take a little getting used to. Other little things like several extra tab loops indicate the thought and field experience that influenced this design. I'll get more into detail about all the features down the road. But first impressions on quality are very good. Materials and craftsmanship are very good. Regarding size, this pack is easily big enough to fit MY needs for several days. When I loaded it up for fitting and to hit the incline trainer, I really just through in everything I had just used last weekend for an overnight backpack trip (in northern Utah....lots of snow and cold). But I added a bunch of extra food and my kill kit to make a point. Without really trying to maximize volume it was too easy to get it all in with quite a bit of room to spare, and I didn't even use the side pockets. This was very useful for me because for the most part that loadout is no different than if it were a 5 day trip, with the addition of maybe 2 pair of socks and a little more food. Bottom line, it's got plenty of room for me. I'll post pics later of what I packed.
I watched Aron's videos on this pack and the frame dozens of times and read the fitting instructions that came with the pack. I also understand that my pack was made to order according to sizing info I gave to Kifaru. So with that information, it is my understanding that they set up the pack for my sizing before they ship it. So with that said, it seems like they got it pretty close. As far as comfort and fit goes, I won't say I put it on and it was instantly a match made in heaven. I still want to try a couple tweaks to the suspension to try and dial in the fit. That's where the time on the incline trainer comes in handy. Its a controlled environment and I can get a good feel for any adjustments made or needed. So I'll keep you posted on that. Specifically, I need to work on the shoulder straps a little to find the perfect fit. The hip belt seems great. Honestly it is quite a bit thinner than I expected, but I had heard that before and it seems quite comfortable. The torso padding and shoulder straps seem good to go.
Separating the bag from the frame is a breeze. Good system there. I tried the hydration thing in between the bag and frame and it was OK, though I don't see myself using that much. I will say, it's a lot easier to set that up with nothing in the bag. Common sense.
Overall first impressions are very good. This is a solid pack of very good quality. No it is not light. Feels about the same as a stripped down USMC ILBE and that's fine with me. I'm really looking forward to loading this up in different configurations, as I feel like there are a lot of capabilities with the compression straps and the side pockets. I'm sure I missed something, so if there's anything you guys want to see or questions, just hit me up and I'll try to address that. I'll keep you posted as I get more experience with this pack.
