I have the version of this backpack from about 5 years ago, and it's still going strong. I've used it heavily for work, hiking, biking, and even as an overnight camping backpack. The side pockets fit a Nalgene bottle pretty well when you don't need a full hydration bladder. I've carried a laptop in this bag on planes, trains, and automobiles with no problems or damage. I've also used some extra webbing to lash tents, climbing gear, bedding, and extra camping gear on some 1-2 night hiking trips where a full internal frame backpack was too much. Mine also has an integrated emergency whistle and reflective panels. Looks like the new version has a bottom loop for an axe or other tool.
Only reason I give it 4 stars is because the elastic on one of the side pockets busted after a few uses with a standard Nalgene. To remedy it, all I did was add a biner to the compression strap and hook it into my Nalgene. Problem solved.
