Query: Review for Rick Steves Civita Day Pack

Initially I thought the day pack was larger but it is really quite small although it does expand to hold quite a bit. I love it because it is small and I can carry it around the city (NY) without being weighed down by a regular backpack but because it expands, it can fit my purchases. The only way I would travel with it would be to carry it on the plane but I wouldn't use it as a travel bag because it is not large enough.
