Looking for suggestions on a backpack that can serve as a daily user for work and as a personal bag for carry on. I don't want anything tactical or mountaineering looking. And I do not like the clam shell style packs. Nothing too big, max 25-28L. Don't want to spend more than $200 if I can avoid it.

The Evergoods Civic Half Zip 22/26L is a good example of what I'm looking for.
