What changes between the published specifications
The published empty-weight values differ by 38.6 g. This compares manufacturer figures; accessory inclusion and weighing tolerance may differ.
Listed capacity: 2 L versus 2 L. Volume ratings do not establish a pocket opening or the shape of an object that can fit.
Outside dimensions stay in the order used by each manufacturer. Match labelled axes where supplied; unlabelled axes do not support a height-to-height claim.
Questions these numbers cannot settle
- Will your phone and passport fit together with the bag fully closed?
- Can you reach the needed pocket while wearing the bag?
- Does the strap adjust comfortably over your clothing and body measurements?
- How does the particular material perform in your use?
Use the two fact sheets for model details, then check those questions with the actual bag or directly with its manufacturer.
