MEI ?
How about the MEI Executive Overniter? Soft-sided convertible travel bag. Excellent shoulder straps, sternum strap, and waist belt, external compression straps, and some organizational pocketrs inside. Lighter than the Air Boss. Also has a luggage pass-through so you can stack it on a roller. I used to be an ardent fan of Red Oxx, but MEI seems to be a little (make that A LOT) more receptive to the customer's needs. 50,000 miles on the bag thus far with no signs of wear...and it hasn't been coddled. Also made in the good 'ole USA.
