Comments about International Traveller International Traveller German Polycarbonate Ultra Lightweight 21.5" Carry On:
I've used this bag as a carry-on for 3 trips now. It's extremely lightweight and easy to maneuver. The bag's weight makes it easier to put into the overhead bin, and the placement and configuration of the toiletries pouch make getting through security very easy.
The only drawbacks are zippers being a bit sticky at times (easily remedied by just shifting how the seams meet), the silver got "scratched" by security belts on my first trip, and the internal capacity (unexpanded)is slightly less than my prior bag's was.
