I currently own a Tumi Alpha Bravo Knox backpack (21L capacity ) which I love. It’s well made, looks sophisticated and just generally suits me well for work every day. The problem is, after also using it extensively as hand luggage over the last few years - it’s not quite big enough for me. So I’m looking for recommendations.

Features that are vital to me:

Handle pass-through so I can easily transport it on top of my wheelie.
Good brand/well made - my Tumi is 4 years old, heavily used and doesn’t even look halfway through its life.
Easy to access 13” laptop and iPad.
Some kind of compression feature so I’m not carting a huge, half-empty backpack between the hotel and the office each day while I’m away.

Cost at not an issue - just looking for the features I need.

Thanks in in advance for any help!
