😀This particular one is a few years old, from British brand Phase Eight. I've seen linen t-shirts in Uniqlo this year, but don't do enough shopping to have other suggestions.
I've heard airlines can be more strict in some European countries about the size of carry on luggage. Have you had any issues traveling with your Away Bigger Carry-on?
I think it's def worth checking the airline's policy ahead of time. It fits easily on British Airways overhead. I've also checked it too. At least when it's this size, I know I can easily lift it and move it myself easily. :)
