We're headed to Italy for two weeks -- and lots of train travel and walking with our bags. Do you have recommendations for smaller-sized carry-on bags (backpack-style or convertible; no wheels or heavy frame) for kids, ages 11 and 8? In a couple of previous trips (with less walking), they were fine with pulling their small rolling bags but now they're capable of carrying a light bag on their backs, which I feel would just be easier than dragging bags from train stations to hotels.
I have the RS convertible carry-on which is OK for me but a little too large for my kids.
Thanks so much for any recommendations!
