What changes between the published specifications

The published empty-weight values differ by 37.5 g. This compares manufacturer figures; accessory inclusion and weighing tolerance may differ.

Listed capacity: 3 L versus 3 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.
