Why compare these options?

- The listed capacities are 40 L and 40 L. Which can take your complete named load with the bag closed? Capacity ratings alone cannot settle this.
- The published empty weights are 1406.1 g and 515 g. Do those figures include the same straps or accessories? Check the source scope before treating the difference as carried weight.

What changes between the published specifications
The published empty-weight values differ by 891.1 g. This compares manufacturer figures; accessory inclusion and weighing tolerance may differ.
Listed capacity: 40 L versus 40 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.
With an illustrative 1 kg load, starting totals would be 2,406.1 g and 1,515 g before any accessories excluded from the published weights. This is arithmetic, not a comfort or packed-load test.
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.
