This pack has thick fabric and looks tough. But looks can be deceiving. The stitching along the back inside walls popped when I used it as checked baggage on a two-hop flight.
The popped seams are visible from the outside. When I looked inside, I found that the reinforcement tape over the seams was not properly aligned, and one of the two rows of stitches was not on the reinforcement tape. So one row of fairly weak thread is all that is holding these two seams together. The whole back wall could come open if they fail.
There are lots of roomy pockets. But all the pockets have only one zipper pull. This means that if the zipper fails, the pockets will be useless. It also mean there is not one pocket that can be locked on the pack.
Beyond that, the design is good, and the pack is reasonably comfortable. But if you are doing any serious hiking or traveling, equipment failure could spell disaster.
This pack is good for light use, lightly packed for short trips or hikes. If you are going to use it for anything else, inspect the seams closely on arrival, and test it out with a full load before venturing out.
