I've had a US Luggage leather laptop bag as current and previous.
Wear pretty well.
Only changed out of the previous one when I didn't need to lug around two 2 inch Jepp binders.
The larger one fit two Jepp binders end to end where the laptop would have gone.
The laptop sleeve/protector inserts slide out and leave a lot of space.
They come in various sizes and with/out wheels.
Plenty of pockets for all the rubbish that seems to accumulate in it.
US Luggage seem to make them in lots of sizes/options.
Big thing for me has always been lots of pockets etc and durability.
Always been great on both.
