- The listed capacities are 20 L and 20 L. Which can take your complete named load with the bag closed? Capacity ratings alone cannot settle this.

What changes between the published specifications
The published empty-weight values differ by 538.6 g. This compares manufacturer figures; accessory inclusion and weighing tolerance may differ.
Listed capacity: 20 L versus 20 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 2,088.6 g and 1,550 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.
