I can only agree with the previous speakers, when it comes to processing and space. All TOP. But: The wearing comfort leaves something to be desired. If the evolution worn as a backpack, he sits very well on the shoulders and is clean to the back. However, the risers scrub (here especially the attached shoulder pads for's "side wear") under / on the arms. With 178 and 76Kg I fall also from any standard with which the scrubbing could be declared.
Abdominal / -Huftgurt: If this closed and drawn, the then "useless rest" of the belt hangs disturbing and there is no decent way to store that part of the belt. The same applies to the shoulder straps.
This is not to belittle I recommend only the backpack out of the box to load and to try before all the signs will be removed and so the excellent overall impression.
