aktchi, just thinking you could get the Valoroso 28" duffel to combine with your tote.

6.7kg though.

Quite the killer bag! The weight seems high but look at it this way. The VS28SAX that I got (hugest suitcase in the line) weighs 5lbs more for the same volume WHEN EXPANDED. So their 28" duffel is still the biggest bag in the line and has a better v/w ratio.
