Is the Champs Vintage IV a true carry-on size?

Yes, it is built as a cabin bag and fits most major airlines' carry-on limits when unexpanded. Expanding it adds depth, so check stricter carriers' sizers before you pack it full.

Is polycarbonate a good suitcase material?

Polycarbonate is light and flexes on impact, so it resists cracking better than hard ABS shells. It does scratch, and glossy black shows marks more than matte or textured finishes.

Does it have a TSA lock?

Yes, a built-in TSA lock is included, so US security can open it without cutting it. You set your own combination.

How many wheels does it have?

Four spinner wheels, so it rolls upright and turns in any direction. It also has a top handle, a side handle and a telescopic handle.

What is inside the case?

A divider and packing straps hold clothes in place on both sides. There is no laptop sleeve or front pocket.

How does it compare with soft-sided carry-ons?

The hard shell protects fragile items and shrugs off rain better than fabric. Soft bags still win on outside pockets and squeezing into tight overhead bins.
