Is it worth it over a basic hard-shell carry-on?

It adds a TSA lock, expansion and organized interior that budget shells lack. If you only need a simple shell, cheaper rivals cover the basics; if you fly often and pack carefully, the extras earn their place.

Will it fit in overhead bins on major airlines?

At 58 cm tall it is near the top of carry-on sizing. It fits most major US and European carriers' overhead bins, but check the specific airline's limit before a budget flight, especially with the expansion open.

How much does the expansion add?

The zip expansion panel adds a few centimeters of depth for extra clothes on the return leg. Close it again for the outbound flight to stay within cabin limits.

Does it have a TSA lock?

Yes, a built-in TSA combination lock is integrated into the shell, so security can open it without cutting anything and you don't need a separate padlock.

What is the shell made of?

The outer shell is polycarbonate with a polyester-lined interior. Polycarbonate is light and flexes on impact rather than cracking, though the glossy finish shows scuffs.

Is it good for a week-long trip?

Yes for warm-weather or light packers who use packing cubes and the compression straps. Cold-weather clothing and bulky shoes will need the expansion or a larger checked bag.
