The biggest difference is that the Metro has a gusseted water bottle pocket inside, while the XS Messenger doesn't. Minor cosmetic differences include one outside buckle on the Metro versus two on the XS Messenger and the attachment of the shoulder strap (fixed on the XS Messenger versus completely removable for the Metro).

One other fundamental difference is that you can customize an XS Messenger on the Build Your Own Bag portion of our website, while all Metros are imported and available in stock colorways only.

All things considered, however, the bags are near substitutes for each other and almost identical in size.
