Why compare these options?
Backpacks of comparable carrying scale, selected for a difference of 1,361.4 g in published empty weight.
- 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.
- The published empty weights are 2010 g and 648.6 g. Do those figures include the same straps or accessories? Check the source scope before treating the difference as carried weight.
- If carrying a laptop, check its actual sleeve and opening dimensions rather than relying on screen size or a laptop-storage label.

What changes between the published specifications
The published empty-weight values differ by 1,361.4 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 3,010 g and 1,648.6 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.
