Wow, this place is amazing! I used my Kuiu bino harness on my Dall hunt and my elk hunt last year. Worked great. Is it the best, I don't know as i have not tried every other harness that is out there. But, I do actually hunt, have used it hunting and have no complaints.
Don,
I used a down bag on my sheep hunt last year in the Alaska range, and slept in a bivy every night. No problems for me. I did change into dry socks before turning in, otherwise I had on my base layers that were often still damp.
I had no problems at all.
I did the same, just watched the video and adjusted with about 30lbs in the pack. I think I have made one or two minor adjustments since then. I have just added the 3 piece belt and cannot believe how awesome it is!
