Why compare these options?
Compare the next Speed Lite size step using manufacturer weight, capacity and dimensions; independent carrying comfort remains unknown.
- Which published empty weight and exterior dimensions fit the limits you need to work within?
- What do your actual load, closure and adjustment checks still need to establish?

What changes between the published specifications
The published empty-weight values differ by 60 g. This compares manufacturer figures; accessory inclusion and weighing tolerance may differ.
Listed capacity: 17 L versus 21 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 1,410 g and 1,470 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.
