PK,
is the garment bag there already? Impressions?
Besides the Redoxx Airboss, I'd like to attract your attention to two equally interesting BR offers.
The 235x, which I own and the review of which you can read in the shoulderbag shoot-out on OBOW.
And the 231x, Double Expandable Tote

The 235x has the larger base dimensions and features a suiter panel among many other things.
The 231x has the smaller base dimensions but can be expanded to 12 inches deep. That will give it roughly the same volume as a 20" rollaboard.
Given that you are going the BR route anyway, I thought I'd let you know.
