I bought this as a carry-on bag for airplane travel, and it's the perfect size.  The quality is very good and the compartments were actually bigger than I expected.

I love new-leather smell, but some people might find it a bit cloying at first. I treated my backpack with leather conditioner right off the bat in order to protect it from the rain and snow that I was certain to encounter in my travels. The leather is a bit stiff being brand new, but after conditioning it and using it quite a bit over a few weeks it softened up nicely.
