While a well-packed carry-on can get you far, the best checked luggage provides ample packing space for long-haul trips.
That means that as much as I hate shopping, I've spent a good amount of time trying to find the perfect luggage for everything from quick road trips to multi-week international adventures.
It also has quiet, easy-to-use wheels, an underside grab handle and a laundry bag for storing dirty clothes while on the road ... suitcase that I have personally used on over a dozen trips ...
