Looks like I am late to the thread but I can add some thoughts on the pack. I have the Yukon Pack and Frame from Wilderness pack specialties. Which I believe is the same pack? Ive always wondered what the main differences area. I cant notice many.
I had them add additional straps so I could pack meat between the bag and frame. They work ok, but not for large loads. The straps arent long enough. For a day back it is bulky. Wide frame and a little noisy but that might be from a few years of use out of it. Straps rub on the frame. Going through thick timber is the only time I wish I had a smaller pack on. Navigating with it on gets frustrating. That belt and pads are comfortable but I would also say, like someone else on here, that the lumbar pad is lacking a bit. Not much support. I have thought about adding more volume behind the lumbar pad to help this. They may have come out with a replacement belt. I would need to look but believe I read that somewhere. I also agree on the load lifters. It helps a bit but for the most part it simply stabilizes the load. I never had an issue with organizing my gear and im still satisfied with the pack. Plenty of separation for me. The material on the pack is really nice and durable. It isnt water proof, just water resistant. I would also say the material is quiet for how durable it is. Ive had no problem carrying enough gear in the 5000 cu in. bag for 8 to 9 days. You can even extend the volume by separating the bag away from the frame (additional straps like I mentioned before). I do find the rifle and bow scab to be worthless. If there is any volume in the pack the bow or rifle doesnt line up and carry very well. A rifle fits nicely for short trips and day hunts with the scope being protected from the mid pocket. that is one nice use of the rifle carrier. I have adjusted my outlook on the pack to want and carry a nice day pack. I will still be using and carrying in the frame but attaching a small pack (spike camp and pouches) that will allow me to drop it off at my camp. I still want the ability to carry bone in quarters out. Its the way I prefer it. Ill attach a few pictures of the frame at work.
