I'm looking for a Travel Backpack

I'm looking for a nice travel backpack to use instead of a standard suitcase. Strapping a backpack on and going is much easier than lugging/wheeling a suitcase around. What do you guys got? Phone Post 3.0

I have a Porter 46 that I use for traveling. It's amazing.

Oh, I also have the Daylight and use that both home and abroad. Although it's just a little smaller than I'd prefer.

I have version 1 of this backpack:

I've used mine for work-related travel, e.g., by plane and by car, and mine works well.

I imagine this version 2 is just as good.




Condor FTW!
