Ok, I sure ain't no big backpacker guy! I had a total knee replacement in 2008 and it still gives me problems, so hauling heavy weights is not something I do much on my back. That's what the horses backs are for! I have been using a little Cabela's elite scout daypack for more years than I can remember, and it has been okay, but it often causes me a lot of shoulder pain. On our elk hunt I noticed that the zipper on the main compartment is having issues, and is likely to open while I am hoofing it somewhere, so I started researching backpacks. Thanks to all of you guys here for all of the information. I have decided on the Stone Glacier Solo. I looked at Kifaru, Mystery Ranch, Kuiu, Exo Mountain, and I just like the looks of the Stone Glacier system best. I don't pack all that much weight on most of my day hunts, but why not have a little extra space and ability to pack out a boned out buck and do it all with the same equipment. I look forward to putting it to good use the rest of the season. Thanks again for all of the information you guys have posted.
