Vek,
A couple things you are seeing there.
One, the load is with the extension collar fully extended, so it is well abouve the stays. Just bulky light weight gear there.
Another thing you are seeing is someone with a severe forward curvature of the cervical. It would be nearly impossible to have a pack that would accomadate my curvature.
I have owned a bunch of Dana's and the KUL 5200 is far more comfortable than any of them were.
