Is the InUSA Vasty good for checked luggage?

Yes. Its size and roughly 10.7 lb empty weight put it in checked-bag territory, and the TSA lock lets security open it without cutting it. It is not a carry-on for most airlines.

How does the ABS and polycarbonate shell hold up?

The blend is lighter and cheaper than full polycarbonate but flexes and scuffs more under rough handling. Expect cosmetic wear on checked trips; a fabric cover helps.

Does it have a TSA lock?

Yes, a built-in TSA-approved lock is part of the shell. You set your own combination, and agents can open it with a master key.

What are the wheels like?

It has four double spinner wheels, so it rolls upright and turns easily in tight spaces. The doubles are wider and can catch on carpet edges and rough pavement.

What is inside the InUSA Vasty?

A full divider and packing straps split the two sides. There are no built-in packing cubes, so add your own for smaller items.

How does it compare with polycarbonate-only suitcases?

It costs less and offers similar space, but premium polycarbonate shells resist cracking and flex better. The Vasty is the value pick if you check a bag a few times a year.
