1. stiff back panel
2. side pocket are difficult to use. Zippers are hard to open, get stuck everytime.
3. there is no cover or zipper for the outer pocket. The water resistant material is meaningless when outermost pocket is open to collect rain, snow and dust which can leaks through to main compartment through the inner material (not water resistant) of the pocket
4. Pockets in the main compartment are very tight. cant use for anything with little bit of thickness
5. the luggage pass through is narrow from the top. It is pain to take it off from trolley bag handle with some grooves. On top of that, the pass through is very stiff.
6. the backpack cant stand on its own
7. the slide through for ipad in the back pocket is small
Lot of hype and big words on official website but this backpack is not very practical. It is a struggle to use this backpack.
If you buy from stmgoods website, it is not easy and definitely not free to return this. You have to pay yourself and they also recommend to have insurance for the package. Means need to pay more.
Definitely not recommended!
