Does it fit major airline carry-on limits?

It is sized as a cabin case and fits most major airlines' overhead limits. Check the specific carrier's dimensions before a tight connection, since some budget airlines are stricter.

Is the shell hard or soft?

It is a hard polycarbonate shell with leather and aluminum trim. That protects contents well but gives no flex when overpacked.

Does it have a TSA lock?

Yes, a built-in TSA lock is included, so security can open it without breaking the case.

How many wheels does it have?

Four double wheels, so it rolls upright in any direction and can be pushed alongside you.

What is the outer compartment for?

A zip-out outer compartment gives quick access to a laptop, documents or a jacket without opening the main packing area.

How does it compare with cheaper polycarbonate spinners?

It adds leather and aluminum detailing and a cleaner look, but basic polycarbonate cases offer similar protection for less and often more internal pockets.
