+1 for the Tumi Alpha Business Class pack. I have had the previous, non T-pass version for 1-1/2 years. Still looks new. The design and construction has kept it from getting sloppy looking. All of the external and internal pockets keep the contents where you want them and easy to access. From a use standpoint, it is very flexible. I can even use it for one bag overnight travel or put a blazer in it using one of Till's jacket folding techniques.
