Why compare these options?

Backpacks of comparable carrying scale, selected for a difference of 258.5 g in published empty weight.

  • The listed capacities are 18.5 L and 18 L. Which can take your complete named load with the bag closed? Capacity ratings alone cannot settle this.
  • The published empty weights are 340.2 g and 598.7 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.

Manufacturer model photographs; pictured colour and size are not independently confirmed. No hands-on winner or rating is assigned.

What changes between the published specifications

The published empty-weight values differ by 258.5 g. This compares manufacturer figures; accessory inclusion and weighing tolerance may differ.

Listed capacity: 18.5 L versus 18 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 1,340.2 g and 1,598.7 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.
