Victorinox NXT 22" replacement
 

So maybe 13 years ago I started using the predecessor model to the Victorinox NXT 22" as my main carry-on. It was great: lots of space, soft shell and expandable, with a removable suiter that was perfect for business travel. When it finally fell apart, I bought an NXT 22" as a replacement. Still roomy, still expandable, but the suiter was no longer completely removable and functionally it was somewhat worse. Nonetheless, there was nothing else close I could find.

The NXT has finally kicked the bucket, and having flown maybe two million miles with these bags I want to buy another one. Alas, I think Victorinox has discontinued the line. The Werks Traveler seems to have very limited space (34L only) due to the caster wheels, and nothing similar exists with a capacity of 45L before expansion. Are there other similar products out there I should try? Given how much I fly, there is no budget as long as it meets all of my requirements.

Thanks
