What remains unknown
- Published weights are empty-bag specifications; included straps, accessories and measurement tolerance may be unstated.
- A low empty weight does not establish capacity, packed comfort, durability or object fit.
- A laptop claim does not confirm a particular device, case, pocket opening, protection or closure fit.
Combined phone-and-passport loading, usable pocket openings, closure, access while worn and fit over winter clothing require their own evidence. Published outside dimensions and capacity do not settle those checks.
