This pack is outstanding and there is only one feature that needs tweaking. The zipper on the lower compartment is a little hard to pull in either direction. Besides this minor complaint this pack has allowed me to get "out" more with my son. The pack seems really comfortable and he usually takes naps everytime we go out. I have put about 30 miles of hiking through the mountains of southern AZ on it with no signs of wear and tear even around the stirrups. I have even used the sun shad as an impromptu changing pad when I forgot my son's pad.
