I had lowa zephyrs, the sole was worn out after a couple of months of walking around the mountains in Utah. Not sure if I got a lemon but they were not very durable. They were very comfortable and could be great for “light days”
I have a marsupial gear bino harness and a hill people gear kit bag, Im able to shoot a bow with either of them with no issues. I really liked the HPG Kit bag for turkey hunting, kept all my calls right where I could access them
I don’t have the Qui-ya but I have the decker and it is very comfortable with 3-4 days worth of gear (most i’ve had in it). I imagine the Qui-ya with the taller frame would be even more comfortable.
