Enroute 23-Liter Backpack

I got this one for air travel mainly, but also for everyday carry at my destination for a couple of days. The goal was a backpack small enough to fit under most airline seats. It might be just a little bit long (or tall if It was standing up) for some seats, such as American Airlines 737s. But maybe not. It should be plenty small enough for Delta a319 or a320. I have yet to take this on a trip, so we'll see. But so far the build quality is excellent, the zippers move nice and smooth, the pockets seem to be well positioned and sized. The interior of the main compartment is larger than I expected. I do wish the organizer had at least one pocket a bit smaller, but it's not a problem.
